Introduction

Voice AI has recently announced their groundbreaking model for speech generation. According to Voice AI, their model is the first Generative AI model that can generalize across tasks with state-of-the-art performance. In this article, we will dive deep into the capabilities and remarkable features of this model.

Speech Generation Model

Voice AI's speech generation model, known as Voicebox, is built upon the latest advancement in non-autoregressive generative models called the Flowing Matching Model. This model enables Voicebox to learn highly non-deterministic mapping between text and speech, allowing it to generate more natural and diverse speech outputs.

Performance Metrics

Voicebox surpasses the state-of-the-art models in terms of two important performance metrics. The first metric is the WORD error rate (WER), which measures the accuracy of the generated speech compared to the target text. Voicebox has a WER that is less than a third of the current state-of-the-art model, Wall E, in English language voice synthesis. For multilingual generation, Voicebox's WER is less than half of its closest competitor, the UTTS model.

The Second metric is style similarity. When comparing the style similarity of Voicebox's English language generation with Wall E, Voicebox outperforms with a higher similarity parameter. This indicates that Voicebox produces speech that closely matches the desired style. Similarly, in multilingual generation, Voicebox excels with a higher style similarity compared to UTTS.

Examples of Zero Shot Text-to-Speech Synthesis

Voicebox presents impressive results in zero shot text-to-Speech Synthesis. This means that given a target text and a short voice input as a Prompt, Voicebox can generate speech that mimics the style of the input prompt. The generated speech sounds natural and coherent. For instance, when prompted with an input to emulate a creative genius, Voicebox successfully generates speech that reflects the desired style.

Cross-Lingual Style Transfer

In addition to English language generation, Voicebox demonstrates the ability to transfer styles across languages. With Voicebox, it is possible to generate speech in French using an English prompt. This groundbreaking feature opens doors for anyone to speak any language using their own voice. Voicebox's ability to transfer styles between languages sets it apart from other speech generation applications.

Noising Dusk

Voicebox provides a unique solution to address transient noise interruptions during speech Recording. With its noising dusk feature, Voicebox can remove transient noise from speech recordings without the need for re-recording. This is achieved by regenerating the noise-corrupted speech and effectively erasing the transient noise. The resulting speech sounds clean and unaffected by interruptions such as doorbells or barking dogs.

Content Editing

Voicebox introduces an innovative content editing capability that corrects spoken words without requiring the speaker to re-Record the audio. This feature is particularly useful in instances where the speaker needs to modify their speech. Voicebox can edit spoken words in real-time, making it a valuable tool for content creators, podcasters, or anyone who relies on speech synthesis.

Diversity of Speech Generation

One of the most impressive aspects of Voicebox is its ability to generate unique and expressive audio styles through sampling. Unlike other models that rely on conditioning on audio data, Voicebox can generate a wide variety of natural-sounding speech styles without any audio conditioning. The resulting speech outputs exhibit rich diversity and can captivate listeners with their expressiveness.

Summary and Conclusion

Voice AI's Voicebox represents a significant advancement in speech generation technology. Its non-autoregressive generative model, combined with the ability to learn from diverse and unlabeled speech data, sets it apart from its competitors. Voicebox outperforms existing state-of-the-art models in terms of accuracy, style similarity, and versatility across languages. With its unique features such as zero-shot Text-to-Speech synthesis, cross-lingual style transfer, noising dusk, content editing, and diverse speech generation, Voicebox solidifies its position as the new standard for speech synthesis.
