The race for the most natural, expressive AI voice has a new frontrunner. We’re thrilled to announce that MiniMax Speech 2.5 HD Preview is now available on WaveSpeedAI, bringing you one of the most advanced text-to-speech models ever created—and it’s ready to use right now with no cold starts, blazing-fast inference, and pricing that makes sense for production workloads.
What is MiniMax Speech 2.5 HD Preview?
MiniMax Speech 2.5 HD Preview is a high-definition text-to-speech model built on an autoregressive Transformer architecture that generates remarkably natural, human-like speech. The model represents a significant leap forward from its predecessor, Speech 02, which already claimed the top position on both the Artificial Analysis Speech Arena and Hugging Face TTS Arena leaderboards—outperforming industry giants like ElevenLabs and OpenAI.
At its core, MiniMax Speech 2.5 HD features a learnable speaker encoder that extracts vocal characteristics directly from reference audio without requiring transcription. This enables zero-shot voice cloning with exceptional fidelity, achieving up to 99% speaker similarity with just 6-10 seconds of sample audio.
Key Features
Unmatched Multilingual Performance
- 40 languages supported including newly added Bulgarian, Danish, Hebrew, Malay, Persian, Slovak, Swedish, Croatian, Filipino, Hungarian, Norwegian, Slovenian, Catalan, Tamil, and Afrikaans
- Industry-leading Chinese TTS widely recognized as the world’s strongest
- Enhanced English synthesis with dramatically improved accuracy, similarity, and natural rhythm
- ~2% Word Error Rate in both Chinese and English
- Seamless language switching within the same generation session
Lifelike Voice Cloning
- Zero-shot cloning from just 6-10 seconds of reference audio (compared to ~60 seconds required by competitors)
- 99% speaker similarity that captures subtle vocal characteristics
- Cross-lingual accent preservation maintaining the speaker’s unique voice even when switching between languages like Italian and English
- No transcription required for reference audio—the model extracts vocal identity directly
Professional-Grade Audio Quality
- HD audio output with crystal-clear articulation and natural pronunciation
- Adjustable controls for speed, volume, and pitch
- Multiple built-in voice options with a rich, multilingual voice library
- Real-time streaming mode for low-latency applications requiring sub-250ms response times
Advanced Prosody and Expression

- Regional accent preservation and special age voice replication
- Long-form synthesis supporting up to 200,000 characters for audiobooks and podcasts
Real-World Use Cases
Content Creation and Media
Transform written content into professional audio at scale. Content creators, podcasters, and publishers can generate hours of high-quality audio content without expensive studio time or voice talent. The long-form synthesis capability makes audiobook production accessible to independent authors and small publishers.
Global E-Commerce and Marketing
With 40 language support, cross-border e-commerce businesses can create localized marketing content, product descriptions, and promotional materials that resonate with audiences in their native languages—all while maintaining brand voice consistency.
Customer Service Automation
Build voice agents and IVR systems that sound genuinely human. The real-time streaming mode delivers the low latency essential for conversational AI, while the clarity and accuracy of MiniMax Speech 2.5 HD ensure customer interactions feel natural rather than robotic.
Dubbing and Localization
Media companies can leverage cross-lingual voice cloning to maintain a speaker’s vocal identity when dubbing content into different languages. An English narrator can be accurately reproduced speaking French, maintaining their distinctive vocal characteristics and accent.
Accessibility
Make written content accessible to visually impaired users with natural-sounding speech synthesis that doesn’t suffer from the monotonous qualities of traditional screen readers.
Gaming and Interactive Media
Game developers can generate dynamic dialogue and NPC voices with emotional expressiveness and real-time performance, enabling more immersive player experiences without recording every possible line.

Why MiniMax Speech 2.5 HD Stands Out
The TTS landscape has evolved dramatically, but MiniMax Speech 2.5 HD has established itself at the forefront. In head-to-head comparisons, it outperforms ElevenLabs in speaker similarity across 24 languages while requiring only 6-10 seconds of reference audio compared to the ~60 seconds needed by competitors. Independent benchmarks show MiniMax achieving an ELO score of 1164 versus ElevenLabs’ 1116 on standardized evaluations.
Perhaps most importantly, this performance comes at significantly lower cost—up to 85% cheaper than comparable solutions—making production-scale voice applications economically viable for businesses of all sizes.
