Features

MiniMax Speech 2.8 Turbo is a high-quality text-to-speech model that transforms written text into natural, expressive audio. With support for multiple voice presets, emotional tones, and fine-grained audio controls, it delivers broadcast-ready speech synthesis for any application.

Why Choose This?

• Rich voice library Choose from 17+ preset voices spanning different genders, ages, and speaking styles — or use your own custom-trained voice.

• Expressive interjections Add natural human sounds like (laughs), (sighs), (coughs), (gasps), and more directly in your text for lifelike delivery.

• Emotion control Set the emotional tone of the speech — happy, calm, or other moods — to match your content.

• Pronunciation customization Define custom pronunciations for brand names, acronyms, or specialized terms using the pronunciation dictionary.

• Full audio control Fine-tune speed, volume, pitch, sample rate, bitrate, channel, and output format for production-ready results.

Best Use Cases

• Audiobook Production — Convert manuscripts into natural-sounding narration with expressive voices.
• Video Voiceovers — Generate professional voiceovers for YouTube, ads, or explainer videos.

• Game & App Development — Add character voices and UI narration to interactive experiences.

Pro Tips

• Use interjections sparingly for natural effect — too many can sound unnatural.
• Match voice_id to your content: use “Deep_Voice_Man” or “Imposing_Manner” for authoritative content, “Lively_Girl” or “Casual_Guy” for friendly content.
• Enable english_normalization when your text contains numbers, dates, or currencies.
• Use pronunciation_dict for consistent handling of brand names or technical terms.
• Start with default speed/pitch settings, then adjust based on your specific use case.

Notes

• Text length affects processing time and cost — longer texts take more time.
• For custom voices, train your voice model first via Voice Clone.
• Interjections must be written in parentheses exactly as listed to be recognized.
