Schema

[Core Function] MiniMax Speech 2.8 Turbo is a lower-latency text-to-speech model with the same control surface as Speech 2.8 HD, including paralinguistic tags such as (laughs). [Strengths] Faster and more cost-efficient synthesis while retaining prosody, timbre mix, pronunciation, subtitle, and audio-format controls. [Best For] Highly recommended for: interactive assistants, high-volume TTS batches, cost-sensitive voiceovers, quick narration drafts, and latency-sensitive product prompts. [Limitations] Do NOT use this for streaming or real-time partial audio. Do NOT request hex output or emotion whisper. Do NOT send both voice_id and timbre_weights. Prefer speech-2.8-hd if maximum audio quality is required. Audio URLs expire in about 24 hours. [Routing] Choose speech-2.8-turbo when the user emphasizes speed, cost, or throughput. Choose speech-2.8-hd for premium quality or highly expressive delivery.

Input

Text to synthesize (fewer than 10000 characters). Supports pause markers such as <#0.5#>, inline pronunciation in parentheses, and paralinguistic tags such as (laughs) or (sighs).
Required when not using timbre_weights (exactly one of voice_id or timbre_weights). Accepts a system, cloned, or AI-generated voice ID. Mutually exclusive with timbre_weights. Full official system voice catalog: https://platform.minimax.io/docs/faq/system-voice-id . Sample system voices (not exhaustive): English_expressive_narrator, English_radiant_girl, English_magnetic_voiced_man, Chinese (Mandarin)_News_Anchor, Chinese (Mandarin)_Lyrical_Voice, Chinese (Mandarin)_Reliable_Executive.
Custom pronunciation rules in original/replacement form, for example omg/oh my god or Chinese pinyin with tone numbers.
Audio bitrate. Applies to mp3 only.
128000
Number of channels. 1 is mono, 2 is stereo.
1
Optional emotion control. Leave unset to let the model choose naturally. whisper is not supported on speech-2.8-hd or speech-2.8-turbo.
emotion
Force constant bitrate encoding. Optional; typically unused for standard async synthesis.
Output audio format. pcmu_raw and pcmu_wav are G.711 mu-law (8 kHz).
mp3
Boost recognition for a language or dialect. Use auto when the language is unknown.
language_boost
Enable LaTeX formula reading (Chinese). When enabled, language_boost may be forced to Chinese. Wrap formulas with $$.
Voice effect: stronger (negative) to softer (positive).
Voice effect: deepen (negative) to brighten (positive). Distinct from pitch (semitone).
Voice effect: fuller (negative) to crisper (positive).
Pitch adjustment in semitones. Distinct from modify_pitch (voice effect slider).
Output sample rate in Hz.
32000
Optional single sound effect applied to the output.
sound_effects
Speech rate multiplier. Higher is faster.
Whether to generate a subtitle file download link.
Subtitle granularity. word_streaming is not supported.
sentence
Enable Chinese/English text normalization for better number reading; may add slight latency.
Required when not using voice_id (exactly one of voice_id or timbre_weights). Mix up to 4 voices by weight. Mutually exclusive with top-level voice_id.
Item 1
voice_id*

Voice ID for one entry in a timbre mix. Distinct from the top-level single-voice voice_id field. May be a system voice from the official catalog (https://platform.minimax.io/docs/faq/system-voice-id) or a cloned/AI voice ID.

weight*

Relative mix weight for this voice. Higher values increase similarity to this voice. At most 4 voices.

Speech volume. Range (0, 10].
