Hume AI has announced the release of Empathic Voice Interface 2 (EVI 2), a major upgrade to its groundbreaking voice-language foundation model. EVI 2 represents a leap forward in natural language processing and emotional intelligence, offering enhanced capabilities for developers looking to create more human-like interactions in voice-driven applications. The release of this new version is a significant milestone in the development of voice AI technology, as it focuses on improving naturalness, emotional responsiveness, adaptability, and customization options for both voice and personality.
Key Features and Advancements
EVI 2 introduces a multimodal approach that seamlessly integrates voice and language processing. This integration allows the system to understand and generate language and handle the nuances of voice, enabling a more natural and human-like interaction. Users can expect the system to converse fluently and rapidly, understanding the tone of voice in real-time and generating appropriate responses, including niche requests such as rapping or changing vocal styles.
One of the most innovative features of EVI 2 is its ability to emulate various personalities, accents, and speaking styles. The model is designed to adapt its personality to match the application’s needs, allowing developers to create engaging and fun conversational experiences. The model’s ability to maintain diverse and compelling personalities makes it ideal for various industries, from entertainment to customer service.
EVI 2 introduces a new voice modulation feature that allows developers to create custom voices. This first-of-its-kind feature lets users adjust the voice along several continuous scales, such as gender, nasality, and pitch, to create unique voices tailored to specific applications or individual users. Importantly, this feature does not rely on traditional voice cloning methods, which have raised concerns over security and ethics in recent years.
Improved Voice Quality and Speed
One of the most notable advancements in EVI 2 is the improved voice quality, achieved through an advanced voice generation model linked to Hume’s language model. The model processes and generates text and audio, producing more natural-sounding speech. This improvement also brings higher expressiveness and better word emphasis, making the system’s responses more human and emotionally intelligent.
EVI 2 has also significantly reduced latency, making it more responsive in real-time conversations. With a 40% reduction in end-to-end latency compared to its predecessor, EVI 2 now averages around 500 milliseconds per response. This improvement makes conversations feel smoother and more natural, enhancing user experience, particularly in fast-paced environments where quick responses are essential.
Emotional Intelligence and Customization
By processing both voice and language in the same model, EVI 2 has enhanced emotional intelligence capabilities. The model can now better understand the emotional context of user inputs, allowing it to generate more empathetic responses. This is reflected in the responses’ content and the generated voice’s tone and expressiveness. The ability to modulate the voice based on the emotional context of a conversation makes EVI 2 a powerful tool for applications that require a deep level of user engagement, such as mental health apps, virtual assistants, or customer support bots.
EVI 2 also offers developers extensive customization options. The ability to dynamically adjust voice characteristics during a conversation allows users to prompt the system to change its speaking style, asking it to “speak faster” or “sound more excited.” This flexibility allows for a more tailored conversational experience, with the voice dynamically adjusting based on user preferences or contextual needs.
Cost-Effectiveness
Despite its advanced capabilities, EVI 2 is more cost-effective than its predecessor. Pricing has been reduced by 30%, with costs now at $0.0714 per minute, down from $0.102 per minute in EVI 1. This cost reduction, combined with the model’s enhanced capabilities, makes EVI 2 a more attractive option for developers looking to integrate sophisticated voice technology into their applications.
Emerging Capabilities and Future Developments
While the current release of EVI 2 is already highly advanced, Hume AI is continuing to improve the model. In the coming months, developers can expect further enhancements, including support for more languages and the ability to handle more complex instructions. As the model scales, Hume plans to make these improvements available to developers, further broadening the range of applications that can benefit from EVI 2’s capabilities.
The EVI 2 API is currently in beta, and while ongoing improvements are being made, developers can integrate the model into their applications immediately. Hume AI has ensured that developers familiar with EVI 1 can easily transition to EVI 2. The system supports all the configuration options available in EVI 1, including supplemental language models and built-in tools like web search.
Migration from EVI 1 to EVI 2
As part of the release, Hume AI has announced that the EVI 1 API will be deprecated in December 2024. Developers currently using EVI 1 are encouraged to migrate to EVI 2. Hume AI has committed to providing clear migration guidelines to ensure a smooth transition, with minimal changes required to make existing applications compatible with EVI 2. The deprecation of EVI 1 is part of Hume AI’s strategy to focus on the future of voice AI technology, with EVI 2 serving as the foundation for all future developments. Developers are encouraged to test EVI 2 to fully utilize the system’s new capabilities before the December deadline.
Conclusion
The release of Empathic Voice Interface 2 marks a significant advancement in voice AI technology. With improved voice quality, faster response times, enhanced emotional intelligence, and extensive customization options, EVI 2 offers developers a powerful tool for creating more human-like and emotionally responsive conversational experiences. As the model continues to evolve, it promises to open up new possibilities for applications across various industries, from customer service to entertainment.
Developers using EVI 1 are encouraged to begin the migration process to ensure continued support and access to new features. With Hume AI’s commitment to ongoing improvements, EVI 2 is set to become a cornerstone in the future of conversational AI, making it an essential tool for developers looking to integrate cutting-edge voice technology into their applications.
