# Inworld STT > Inworld's speech-to-text API runs its inworld/inworld-stt-1 model in 30 languages over synchronous HTTP, bidirectional WebSocket streaming and asynchronous jobs, returning Voice Profile signals (age, emotion, pitch, accent) and turn detection alongside the transcript. - Canonical: https://www.anchorterminal.com/tools/inworld-stt - Pricing: https://www.anchorterminal.com/tools/inworld-stt#pricing - Reviews: https://www.anchorterminal.com/tools/inworld-stt#reviews - Markdown: https://www.anchorterminal.com/tools/inworld-stt.md (~7,250 tokens) - Slim: https://www.anchorterminal.com/tools/inworld-stt.min.md (~1,430 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/inworld-stt.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (the key docs and every listing in one file, at most 16 MB, about 4 million tokens: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - MCP: https://www.anchorterminal.com/mcp (the whole catalogue as tools, no key) - DNS: dig +short TXT inworld-stt.grade.anchorterminal.com (the grade as a DNS TXT record, for a sandbox with no HTTP where names still resolve; also top., best.. and .vs.. under the zone, and the same under grade.letme.dev) - Licence: CC BY 4.0, credit Anchor Terminal and link this page (https://www.anchorterminal.com/terms/#data) - Updated: 2026-11-07 ## Overview **Grade C · 54.7/100 · rank #895 of 1486 · #16 in Speech-to-text · not agent-ready · confidence medium** More from Inworld AI, listed separately because each is its own product: [Inworld Realtime TTS-2](https://www.anchorterminal.com/tools/inworld-tts.md) (Text-to-speech), [Inworld Realtime API](https://www.anchorterminal.com/tools/inworld-realtime.md) (Conversational voice agents), [Inworld Instant Voice Cloning](https://www.anchorterminal.com/tools/inworld-voice-cloning.md) (Voice cloning & custom voices). ## Assessment Inworld STT costs $0.10 to $0.15 an hour with 400 free minutes, and covers files, live streams and async jobs in 30 languages with Voice Profile signals. There is no machine-readable spec, no public STT changelog and no readable status history, and diarisation is still experimental. ## Facts | Field | Value | | --- | --- | | Vendor | Inworld AI (https://inworld.ai) | | Kind | Model API | | Category | Speech-to-text (https://www.anchorterminal.com/categories/speech-to-text) | | Transport | HTTP, websocket | | Auth | API key · Every call sends `Authorization: Basic` with the Base64 `key_id:secret` credential from the Portal or the CLI.

On-Demand includes up to 400 minutes free. Diarisation and Voice Profile are separate per-second add-ons. Asynchronous jobs need a payment method. | | x402 | No · No x402, MPP or L402 in the docs, llms.txt or pricing page (checked 2026-11-06).

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 60 | 12.0 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 54 | 8.8 | | Agent ergonomics | 13% | 16.2 | 56 | 9.1 | | Security & auth | 14% | 17.5 | 63 | 11.0 | | Payments & pricing | 10% | 12.5 | 40 | 5.0 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 41 | 3.6 | | Transparency & trust (editorial 45, provenance 75) | 7% | 8.8 | 60 | 5.2 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **54.7 → C** | ### Why each score - Reliability 60 (checked 2026-11-06): Hosted reading of the checklist. status.inworld.ai is a public status page (20), and as on inworld-tts its history draws on GitHub issues we couldn't read, so no readable history (5). Streaming concurrency is published per plan, 10 on On-Demand up to 1,000 on Growth, shared across keys (15). 429 and gRPC code 8 are documented with exponential backoff and jitter, and Retry-After only on longer windows (12 of 15). An SLA appears only in the Enterprise column of the pricing table, with no terms (0). STT-1 carries no preview label, but diarisation is experimental and async jobs poll a `v1alpha` operations route (8 of 10). 20 + 5 + 15 + 12 + 0 + 8 = 60. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 54 (checked 2026-11-06): No OpenAPI or other machine-readable file. The usual spec paths redirect, and the reference pages are Markdown (0). llms.txt, Markdown twins and a docs MCP server (10). Guides say when to use sync, streaming or async, how the language hint behaves and that a malformed first frame closes the socket silently (16 of 20). The reference marks types and required fields, with an encoding list and a 16 MB limit, but `modelId` is a free string (12 of 15). Examples in Python, JavaScript and curl, a gRPC code table and WebSocket error frames, with no per-endpoint error list (11 of 15). Versioned `/v1` paths, but the STT release notes path redirects to a Portal login and no public STT changelog was found (5 of 15). Total 54. - Agent ergonomics 56 (checked 2026-11-06): API reading of the checklist. Voice Profile, word timestamps and diarisation are opt-in, and responses carry a `usage` block (18 of 25). No lists to page. Async jobs return an operation to poll (8 of 20). Errors carry a numeric gRPC code and message on both endpoints, but a malformed first message closes the socket with 1005 and no frame (12 of 20). Sync calls are stateless and async calls return an operation, with no idempotency key, and empty transcripts and add-ons are billed (10 of 20). A call needs a model, an encoding and the audio. No STT SDK was found, only the CLI and its MCP server and REST examples (8 of 15). Total 56. - Security & auth 63 (checked 2026-11-06): Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Workspace API keys sent as Basic credentials, deleted to revoke, with separate keys per environment advised. The CLI mints read-only keys unless `--write` is given, but write toggles cover only the Voice and Router APIs, so no key is limited to one product. Browsers use short-lived tokens minted server side, via the `bearer_` WebSocket subprotocol, not the URL (25 of 30). The Terms (11 June 2025) say Inworld won't train generally available models on customers' non-public Materials, except feedback and flagged content, while the Privacy Notice (18 January 2026) lists training AI models among its uses, per the inworld-tts check of 4 November (12 of 20). Zero data retention keeps STT audio and transcripts in memory and out of logs, included on Developer ($300 a month) and above per the docs, while the STT page says Enterprise or a Growth add-on. Async results and audio go after 7 days, and no default period is given for logs (8 of 15). Usage is attributed per key and a Performance page shows errors and throttling (8 of 15). SOC 2 Type II and HIPAA claimed and a vulnerability report form, with no security.txt or bug bounty, per the 4 November reading (10 of 20). Total 63. - Payments & pricing 40 (checked 2026-11-06): No x402, MPP or L402 (0). Per-hour prices for every plan published without a login (20). On-Demand includes up to 400 minutes of STT and lists no payment method, while async jobs need one (20). A person signs up in the Portal or through `inworld login` in a browser before a key exists (0). Total 40. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 41 (checked 2026-11-06): Read as a model. No public STT changelog. The newest dated change touching STT is the Realtime note of 14 September 2026 fixing STT-1 turn detection, 53 days ago (20). The CLI, which carries the STT command and MCP tool, shipped 1.4.0 to 1.5.0 between 13 and 29 October, counted half as client releases, and no dated STT entries were found (5 of 20). Discord and support@inworld.ai, with no evidence of answers read (6 of 15). No official STT SDK; the CLI is current (5 of 15). CLI on npm under MIT, current, CI not read (5 of 10). Total 41. - Transparency & trust 60 (checked 2026-11-06): Closed service with clear terms naming Theai, Inc. dba Inworld AI (15). The ZDR page states what STT keeps, but the terms and privacy notice disagree on training, and the docs and the STT page disagree on which plans include zero retention (12 of 30). No dated STT deprecation or change notices are public (8 of 20). US headquarters with EU and India residency on Enterprise, and no sub-processor list in the docs (10 of 20). Total 45.

Inworld's Realtime TTS-2 page, read 30 October 2026, quotes Kylan Gibbs as CEO of Inworld AI. Inworld's Series A release of 23 August 2022, as published by Intel Capital, names Ilya Gelfenbeyn, Michael Ermolenko and Kylan Gibbs as founders and Ilya Gelfenbeyn as CEO at the time. No about or team page was found in the inworld.ai sitemap, so the present roles of the other two founders aren't established and the roster may be incomplete. No personal accounts are linked from Inworld's pages, so none are listed. The 28 October 2026 Reasoning post is signed by the Inworld TTS team. The ultravox listing's humans file records Inworld's announcement of 30 September 2026 that it acquired Ultravox. Investors come from the Series A release as published by Intel Capital and from The SaaS News report of the August 2023 round led by Lightspeed. Business Wire and GlobeNewswire, which carry Inworld's own releases, answered robots.txt with 403 and weren't read, so the pre-seed and seed rounds aren't itemised, and Meta is listed without a round. GamesBeat's report of 2 August 2023, read 6 November 2026, says the Lightspeed-led $50 million round brought the valuation to over $500 million and that Inworld had over $100 million in total funding; those are given as the valuation and total raised. It also quotes Michael Ermolenko as CTO and cofounder at the time. No later round was found. - Inworld AI (Theai, Inc.): LinkedIn https://www.linkedin.com/company/inworld-ai X https://x.com/inworld GitHub https://github.com/inworld-ai ### Ownership and investors - Raised: over $100M in total, as of August 2023 (source https://gamesbeat.com/inworld-ai-raises-new-round-at-500m-valuation-for-ai-game-characters/) - Valuation: over $500M as announced (the source doesn't say pre- or post-money), August 2023 round led by Lightspeed, August 2023 (source https://gamesbeat.com/inworld-ai-raises-new-round-at-500m-valuation-for-ai-game-characters/) - Backed by: Section 32, Intel, Lightspeed Venture Partners, Founders Fund, Accelerator Investments LLC, First Spark Ventures, Kleiner Perkins, BITKRAFT Ventures, CRV, Microsoft, Micron, LG, SK Telecom, The Venture Reality Fund, HTC, Meta, Stanford University, Samsung, The Walt Disney Company, NTT DOCOMO ### Getting support - Discord: https://discord.gg/inworld - Support email: support@inworld.ai - Help: https://docs.inworld.ai/portal/support - Help: https://docs.inworld.ai/ - Sources: https://inworld.ai/blog/realtime-tts-2, https://inworld.ai/blog/realtime-tts-2-reasoning-speed-consistency, https://inworld.ai/pricing, https://inworld.ai/terms, https://inworld.ai/security, https://inworld.ai/sitemap.xml, https://docs.inworld.ai/portal/support.md, https://www.intelcapital.com/inworld-ai-closes-50m-series-a-to-populate-video-games-and-the-metaverse-with-interactive-ai-driven-characters/ ## Live (updated 2026-11-07 16:01 UTC) - npm `@inworld/cli` 1.5.0 - security.txt: none - Always current: https://www.anchorterminal.com/api/v1/live/inworld-stt.json ## Probe metrics Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | STT-1, On-Demand | $0.0025 | per minute of audio | $0.15 an hour | | STT-1, paid plans | $0.0017 | per minute of audio | $0.10 an hour on Creator to Growth | Across all listings: https://www.anchorterminal.com/prices/index.md ## What a task costs (from the prices above) | Task | Cost | At | | --- | --- | --- | | Transcribe a one-hour meeting (60 minutes of recorded audio) | $0.10 to $0.15 | STT-1, paid plans to STT-1, On-Demand | The quantity times this listing's own price, from its cheapest item in that unit to its dearest. Plans, minimums and free allowances aren't counted. ## Strengths - $0.15 an hour on the free plan and $0.10 on paid plans, billed per second, with 400 free minutes - Sync, WebSocket streaming and async jobs on one model, with turn detection and Voice Profile signals - Browser tokens travel in a WebSocket subprotocol, not the URL - Zero data retention keeps audio and transcripts in memory, and the docs include it from the Developer plan - llms.txt, Markdown twins and a docs MCP server ## Weaknesses - No OpenAPI or other machine-readable contract - The STT release notes path asks for a login, so changes to the model aren't publicly dated - Status history couldn't be read, and an SLA exists only for Enterprise - Speaker diarisation is experimental and async jobs run on a `v1alpha` operations route - Docs and the STT product page disagree on which plans include zero data retention ## Before you call it (notes for agents) 1. Send the Base64 credential as-is in `Authorization: Basic`; don't encode it again 2. Wrap the first WebSocket message in `transcribeConfig`, because a malformed first frame closes the socket with 1005 and no error 3. Use `POST /stt/v1/transcribe:async` for files over about 16 MB and collect the transcript within 7 days 4. Retry 429 or gRPC code 8 with exponential backoff and jitter, and stay within the plan's streaming concurrency 5. Stop sending audio when nobody speaks, since streams are billed for every second sent ## Connect Install: ```bash npm install -g @inworld/cli ``` Claude Code: ```bash claude mcp add inworld -- inworld mcp ``` ## Similar tools Ranked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on inworld.ai or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "inworld-stt", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
