Together AI announces integration of Rime Arcana v2 and Mist v2 models to improve text-to-speech capabilities, offering enhanced expressivity and pronunciation control for enterprise applications.
Together AI has introduced two advanced Rime text-to-speech (TTS) models, Arcana v2 and Mist v2, into its platform, enhancing its AI Native Cloud offerings. These models, as reported by Together AI, aim to provide enterprise-grade voice solutions with improved expressivity and pronunciation accuracy.
Advancements in TTS Technology
Arcana v2 and Mist v2 are designed to integrate seamlessly with existing large language models (LLM) and speech-to-text (STT) systems, allowing users to manage their voice technology infrastructure more efficiently. The models are hosted on Together AI’s dedicated cloud infrastructure, ensuring low latency and high reliability essential for enterprise applications.
Arcana v2: Enhanced Conversational Expressivity
Arcana v2 is tailored for expressivity, offering over 40 voices in multiple languages and dialects to cater to diverse customer service scenarios. It is particularly effective in environments requiring nuanced conversational abilities, such as sales and support, where it has shown to improve metrics like sales conversion and call success rates.
Mist v2: Precision in Pronunciation
Mist v2 focuses on deterministic pronunciation, essential for high-volume applications where consistency is critical. This model allows users to define pronunciation once, ensuring uniformity across different voices and platforms. Such precision is crucial in sectors like healthcare and finance, where accurate communication is vital.
Impact on Enterprise Applications
Both models are already deployed across various industries, from Fortune 500 companies to startups. Arcana v2’s capability to enhance conversational interaction has led to significant improvements in customer engagement. Meanwhile, Mist v2’s reliability in pronunciation control supports high-stakes environments such as customer service and interactive voice response (IVR) systems.
Infrastructure and Compliance
Together AI provides a robust infrastructure supporting these models, with dedicated GPU resources and compliance with SOC 2 Type II and HIPAA standards. This setup ensures that enterprises can deploy voice solutions that meet stringent regulatory requirements while maintaining high performance and uptime.
Future Prospects
With the integration of these models, Together AI continues to advance its platform, offering a comprehensive suite of voice solutions that cater to the varied needs of enterprises. This development marks a significant step forward in the evolution of AI-driven voice technologies, promising more natural and effective interactions in automated systems.
