minimax-speech

minimax-speech is a skill for Claude Code, Codex from calesthio/generative-media-skills. It costs 105 tokens per session (5,618 once invoked), scanned A, original, MIT.

A guide to MiniMax speech APIs, which turn text into spoken audio through regular HTTP requests, realtime WebSocket streams, or asynchronous long-form jobs. It covers system voices, cloned voices, text-designed voices, and voice cloning.

In plain words
What is it for?
Use it for narration, dubbing, localized voiceovers, advertising reads, audiobooks, product walkthroughs, voice-agent responses, and approved voice cloning.
Why use it?
It helps developers select the right delivery method for short, realtime, or long-form speech. It also keeps speech work separate from MiniMax’s video, music, image, and general language-model services.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

minimax-speech scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MiniMax speech production

Use MiniMax when the production goal is generated speech: narration, localized VO, ad reads, audiobook-style segments, synthetic dialogue, product walkthroughs, voice-agent responses, or approved voice cloning. Do not use this skill for MiniMax video, music generation, image generation, or general LLM calls except where they affect speech production.

The facts below were verified against official MiniMax API documentation, release notes, pricing, and policy pages on 2026-07-10. Treat model IDs, prices, rate limits, retention windows, voice lists, and policy language as volatile; re-check before a paid or regulated production run.

Capability boundary

Documented MiniMax speech capabilities:

  • Synchronous text-to-audio over HTTP: POST https://api.minimax.io/v1/t2a_v2.
  • Synchronous text-to-audio over WebSocket: wss://api.minimax.io/ws/v1/t2a_v2.
  • Asynchronous long-form text-to-audio: create a task with POST /v1/t2a_async_v2, query it, then retrieve the generated file.
  • System voices, cloned voices, and text-designed voices, queryable through Voice Management.
  • Rapid voice cloning through file upload plus POST /v1/voice_clone.
  • Voice design through POST /v1/voice_design, where a text description produces a generated voice_id and preview audio.
  • Subtitle timestamp generation from TTS (sentence, word, or word_streaming depending on streaming mode).
  • An ASR-based validation check inside voice cloning when text_validation is provided.

Not documented as standalone production APIs in the official docs index as of 2026-07-10:

  • Standalone speech recognition / transcription.
  • Speech-to-speech dubbing.
  • Voice conversion from arbitrary source speech to a target voice while preserving timing.
  • A separate low-latency conversational turn-taking API beyond T2A WebSocket streaming.

If a user asks for transcription, voice conversion, or full dubbing, combine MiniMax TTS with another documented ASR/alignment/dubbing provider, or explain that MiniMax’s official speech surface does not currently expose that workflow directly.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
