Giving Voice Imagination: MiniMax Launches Voice Foundation Model | Oasis Vitality

MiniMax has unveiled a next-generation voice foundation model that surpasses traditional text-to-speech technology, offering voice synthesis and voice cloning services.

MiniMax's voice foundation model can deeply comprehend human language, precisely capture and learn thousands of vocal timbre characteristics, and freely combine them to generate infinite variations of voice, emotion, and style. It skillfully displays multifaceted personalities and is fluent in eight languages. The model has already been deployed in commercial applications such as the STARFIELD app, Qidian, and Gaotu Techedu, demonstrating formidable capabilities across more than ten scenarios including social networking, podcasts, audiobooks, news, education, and digital humans.

Challenges of Traditional Voice Synthesis

Mechanical quality: Sacrifices some naturalness of human voice, lacking emotional expression

Limited timbre range: Low scalability in generated voices, making it difficult to meet diverse scenario demands

Low efficiency: Cloning requires professional recording studios and equipment, with high costs and lengthy timelines

Three Key Highlights of MiniMax Voice Foundation Model

Powered by next-generation AI foundation model capabilities, MiniMax's voice foundation model can intelligently predict text emotion, intonation, and other information based on context, generating hyper-natural, high-fidelity, personalized speech. Compared to traditional voice synthesis technology, MiniMax's voice foundation model achieves a new synthesis height of "AI" indistinguishable from human voice with greater precision and speed in audio quality, breathing pauses, and prosodic rhythm, delivering a more vivid and emotionally expressive auditory experience.

Hyper-natural, High-fidelity

It understands the intricacies of human language deeply — whether complex meanings or emotions, tones, even laughter hidden between the lines, all are captured with perfect appropriateness. By combining punctuation and contextual cues, it comprehensively interprets the emotional world behind text: light and passionate, or low and sorrowful... presenting it all with natural intonation. More intriguingly, in special contexts, it can demonstrate dramatic vocal tension — as you'll hear below, when a speaker is doubled over laughing at a friend's joke, it can match this exaggerated emotion with hearty laughter of its own.

Diverse, Highly Extensible

By learning from a certain volume of parameters, it can precisely capture the unique characteristics of thousands of timbres and freely combine them, effortlessly creating infinite variations of voice, emotion, and style. It not only masters multiple languages including Chinese, English, German, and French, but also expresses rich and diverse personality traits through voice — whether a cool and alluring mature woman, a gentle spring-breeze-like female anchor, a green and innocent male college student, or a steady and profound male host, it switches at will while maintaining clarity, stability, and expressiveness. Across diverse scenarios such as social networking, podcasts, audiobooks, news, education, and digital humans, it displays fully realized vocal charm.

Low Cost, High Efficiency

No professional recording environment or equipment needed — our rapid cloning service operates under minimal conditions, requiring only 30 seconds of recorded audio to complete voice cloning. The generated voice is highly similar to the original timbre, dramatically reducing time and capital investment to meet users' basic needs for self-voice or copyrighted voice replication.

Industry Cases

1. Voice Chat Social — Partnered with STARFIELD APP to create hundreds of personalized CV voiceovers, privately customized character voices

Partnered with STARFIELD APP to launch personalized voices for hundreds of characters; beyond this, users can freely mix and match from dozens of base voices according to their preferences to customize exclusive character voices. Custom character voices can be mixed from dozens of distinct base voices across three dimensions — gender, age, and style — generating diverse character voices that are aloof, sweet, mature... for an immersive auditory experience.

2. Audiobooks — Partnered with Qidian to create AI voice personas "Storyteller" and "Miss Fox," bringing vivid audiobook experiences

Collaborated with Qidian to develop AI narration voices "Storyteller" and "Miss Fox," completing audiobook production for multiple finished novels and full-chapter serialized works from top titles. During long-text chapter generation, the voice foundation model maintains coherent contextual understanding while accurately parsing dialogue context and emotion, enabling rapid generation and output.

3. Education — Partnered with Gaotu Techedu to create AI postgraduate entrance exam digital human "Teacher Wenyong," accompanying students throughout their exam journey

Collaborated with Gaotu Techedu to develop AI postgraduate entrance exam digital human "Teacher Wenyong," enabling interactive teaching through 1-on-1 Q&A. "Teacher Wenyong" provides one-stop solutions for key preparation stages including lectures, Q&A, intelligent problem recommendation, assessment and learning analytics, and full-simulation exam environments, offering millions of aspiring students a vivid, smooth, and personalized learning experience.

Stable, Accurate, and Fast Voice Cloning

Unlike traditional TTS voice cloning, our large language model-based voice cloning is more stable, precise, fast, and outstanding in effect. It requires neither hours of ultra-high-quality original audio nor excessively long turnaround times — instead, it can craft a unique voice replica for you in minimal time. Leveraging the powerful capabilities of foundation models, we can achieve high-quality restoration of original voices, precisely reproducing everything from prosodic rhythm to accents and speech habits. Whether for broadcast hosts, educators, IP replication, or digital human needs, we can create charismatic audio experiences. Currently, we offer two cloning modes for clients with different needs.

1. Rapid Cloning Service: Supports cloning from 30-second audio samples, generating speech close to the cloned voice to meet basic user needs for self-voice or copyrighted voice replication

2. Premium Cloning Service: Supports cloning from 20-minute audio samples, fully restoring authentic accents, speaking styles, and related vocal characteristics. Most suitable for host recording, teacher voice restoration, IP replication, and similar scenarios

Fluent in Eight Languages

We can currently easily handle voice generation in more than 8 languages. Whether Mandarin, English, German, French, Spanish, Indonesian, Portuguese, or Russian... we accurately capture the unique pronunciation characteristics of each language and express them fluently.

Beyond mastering multiple languages, our large voice model can also freely switch between different languages, achieving true multilingual mixed voice synthesis to adapt to more scenario needs.
