MiniMax Speech 2.5 Turbo Preview
MiniMax's high-definition text-to-speech model with natural pronunciation and clear articulation. Features multiple voice options, adjustable speed, volume, and pitch controls for professional-grade audio generation.
Features
Three major breakthroughs: stronger multilingual performance, more lifelike tone, and 40 languages covered — now with real-time streaming capabilities for low-latency audio generation.
Leapfrogging multilingual performance
- Chinese is the world's strongest, English and other languages have been comprehensively improved in terms of accuracy, similarity, and natural rhythm, surpassing the previous generation Speech 02.
- English similarity has been significantly improved, and 40 languages can be switched at will, making it no longer "mechanical" in commercial meetings, daily conversations, and English podcasts.
Lifelike tone replication
- Across languages, accents, styles, and emotions, with industry-leading precision in detail.
- The model can still achieve "voice"-like realism in extreme scenarios, such as cross-language accent preservation, regional accent preservation, and special age voice replication.
40 languages are now supported
- Diversified high-quality audio library, globalized and unobstructed.
- New additions include Bulgarian, Danish, Hebrew, Malay, Persian, Slovak, Swedish, Croatian, Filipino, Hungarian, Norwegian, Slovenian, Catalan, Nynorsk, Tamil, Afrikaans......
- Cross-border e-commerce, overseas customer service, and localized marketing are now easier than ever with globalized content creation at your fingertips.
- Streaming mode: generate and play audio as it’s being synthesized for real-time applications.

Speech 2.5 Turbo Preview API — Quick start
Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/minimax/speech-2.5-turbo-preview with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Speech 2.5 Turbo Preview below.

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/minimax/speech-2.5-turbo-preview" \

What is the Speech 2.5 Turbo Preview API?
Speech 2.5 Turbo Preview is a MiniMax model for audio generation, exposed as a REST API on WaveSpeedAI. Minimax Speech 2.5 Turbo Preview: HD TTS with multilingual support, accurate voice replication across 40 languages. $0.04/1000 chars. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
How do I call the Speech 2.5 Turbo Preview API?
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/minimax/minimax-speech-2.5-turbo-preview.
How much does Speech 2.5 Turbo Preview cost per run?
Speech 2.5 Turbo Preview starts at $0.040 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
What inputs does Speech 2.5 Turbo Preview accept?
Key inputs: `bitrate`, `channel`, `emotion`, `enable_sync_mode`, `english_normalization`, `format`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/minimax/minimax-speech-2.5-turbo-preview.
How long does Speech 2.5 Turbo Preview take to generate?
Average end-to-end generation time on WaveSpeedAI is around 22 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.
Can I use Speech 2.5 Turbo Preview outputs commercially?
Commercial usage rights depend on the model's license, set by its provider (MiniMax). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
