MiniMax Speech (T2A) vs Resemble AI Text-to-Speech API

MiniMax Speech (T2A) 20

No x402, MPP or L402 (0). Per-character prices for every speech model published without a login (20). No free allowance for synthesis is published (0). A person signs up in a browser and funds a balance (0). Total 20.

Resemble AI Text-to-Speech API 0

No x402, MPP or L402 (0). The per-second prices ($0.00067 on Flex, $0.0005 on Team and Business) were read on 30 September from app.resemble.ai/billing/api/v1/plans, a billing data endpoint this run doesn't read, so that reading is struck, and the pricing pages can't be re-read under the terms, so no per-unit price stands today (0). No free synthesis allowance per the 1 October check (0). A person signs up in a browser (0).

MiniMax Speech (T2A) 36

Model reading of the checklist, with training and retention in place of the least-privilege and injection lines. Plain API keys with no scopes found, and leaked keys may be disabled (20 of 30). The terms (effective 30 March 2026), as read for minimax-voice-cloning on 4 November, let MiniMax use input and generated content to operate, maintain, develop and improve its services, with no opt-out found, and the privacy policy rules out only training to profile or target consumers (5 of 20). The speech docs call every interface stateless, and no retention period for submitted text or generated audio was found (5 of 15). Responses carry usage_characters and a trace ID, with no audit log (6 of 15). No security.txt, disclosure policy, bug bounty or certification found (0 of 20). Total 36.

Resemble AI Text-to-Speech API 48

Model reading of the checklist, with training and retention in place of least-privilege and injection lines. One Bearer key with no scopes found (20 of 30). The privacy policy (14 August 2026) says customer voice data isn't used to train general-purpose models, worded for voice data rather than text (15 of 20). Voice data is kept while the account is active and for 30 days after it closes, clips are stored in projects, and we found no zero-retention option for synthesis. The Node SDK's zero_retention_mode (3.5.3) is a detection option (5 of 15). No per-call log found (0 of 15). Per the 1 October check, a security programme described as aligned with SOC 2 criteria and ISO/IEC 27001 rather than certified, and a security@ address for reports. No security.txt (8 of 20). Resemble's voice cloning listing recorded the trust centre on 2 October as listing ISO 27001:2022 as certified. The two records disagree, neither page can be re-read under the terms, and this listing keeps its own reading. OSV lists no records for @resemble/node or resemble (4 November). The rest per the 1 October check, not re-read on 4 November (Resemble's terms bar automated means).

MiniMax Speech (T2A) 56

API reading of the checklist. Audio comes back hex-encoded inside JSON by default, with subtitles opt-in and format, bitrate and sample rate settable (15 of 25). Voices are listed by type through POST /v1/get_voice, which has no pagination and returns 300+ system voices for all (10 of 20). Errors come as numeric codes in base_resp with a short remedy for each, inside responses documented only as 200 (13 of 20). No idempotency key, and the MCP tools carry no read-only or destructive annotations (10 of 20). Two required fields. No official SDK for speech, with MCP servers in Python and JavaScript (8 of 15). Total 56.

Resemble AI Text-to-Speech API 46

API reading of the checklist. WAV or MP3 from 8 to 48 kHz at 16, 24 or 32-bit, but synchronous synthesis returns the whole clip as base64 inside JSON (18 of 25). 2,000 characters per synchronous or HTTP stream request, 3,000 per WebSocket message. Longer scripts go through projects and clips (10 of 20). Errors are a boolean and a message, with advice to log the request ID (5 of 20). No retry, idempotency or billing-on-failure guidance found (0 of 20). Two required fields, a voice UUID and the text, and SDKs in Node and Python (13 of 15). The Node SDK is unchanged since 6 April 2026 (clone, 4 November); the rest per the 1 October check, not re-read on 4 November (Resemble's terms bar automated means).

MiniMax Speech (T2A) 38

Read as a model, as minimax-voice-cloning is. The newest dated change touching speech is the MCP servers' August update, minimax-mcp-js 0.0.18 on 21 August 2026, 77 days before 6 November, and Speech 2.8 dates from 23 January 2026 (20 of 30). No dated API entries in the last 90 days (0). Support by email and Discord, not tested (6 of 15). No official SDK for speech; the MCP servers expose text_to_audio and list_voices (8 of 15). The Python MCP server has tests and moved to version 2 of the MCP SDK in August, with no CI workflow (4 of 10). Total 38.

Resemble AI Text-to-Speech API 31

Read as a model. The newest changelog entry is 2026-06-30 per the 1 October check, not re-read on 4 November (terms), 127 days old (10). No dated entries in the last 90 days that we could read (0 of 10). Older models were deprecated on 2026-06-29 and the docs say voices on them can't generate until upgraded, with no effective date published (0 of 10). Public changelog and a support address, SDK issue trackers not checked (8 of 25). The Node SDK clone on 4 November still ends at 754a91e (6 April 2026, 3.5.3); Python 1.9.0 of 6 April per the 1 October check, not re-read. Neither has a release since the June model changes (10 of 15). The Python SDK still declares support from Python 3.6, and the Node repository has no CI workflow and no release tags (3 of 10).

MiniMax Speech (T2A) 81

OpenAPI 3.1 for the sync and async routes and AsyncAPI files for the WebSocket and bidirectional sockets (25). llms.txt and a Markdown copy of every page (10). The text field says when to stream and how to mark pauses, and guides separate sync, WebSocket and async use (15 of 20). Enums for model and audio settings, with model and text required (13 of 15). Examples throughout and the shared table of error codes, but the OpenAPI file documents only a 200 response (10 of 15). Versioned /v1 paths. The API release notes stop at 28 October 2025, and the last T2A entry is 23 September 2025 (8 of 15). Total 81.

Resemble AI Text-to-Speech API 75

OpenAPI file in JSON and YAML at docs.resemble.ai (25). llms.txt with Markdown pages (10). The docs separate synchronous, HTTP streaming and WebSocket synthesis and say WebSocket needs Business, but rarely say when not to use one (12 of 20). Request bodies typed in the spec. The model is chosen by the voice, not the request (12 of 15). Examples on each endpoint, but the errors page only describes success: false with a message and lists no status codes (6 of 15). /api/v2 paths and a dated product changelog shared with detection (10 of 15). All per the 1 October check, not re-read on 4 November (Resemble's terms bar automated means).
