Description
The Azure Voice Live API offers a comprehensive, managed platform for creating high-quality, low-latency speech-to-speech agents, all through a single, unified interface. By integrating speech recognition, generative AI, and text-to-speech capabilities, it enables developers to effortlessly send audio inputs and receive synchronized audio outputs, along with avatar visuals and action triggers, while eliminating the need for separate backend orchestration or model deployment. This robust solution supports over 140 speech-to-text languages and features more than 600 standard voices across 150+ text-to-speech languages, providing options for custom speech, phrase lists, unique voices, and avatars that align with brand identities. Developers have the flexibility to select from various generative AI models, such as GPT-Realtime, GPT-5, GPT-4.1, GPT-4o, Phi, and other compatible bring-your-own models, tailored to meet specific needs for intelligence, speed, and latency. The API also incorporates advanced conversational features like noise suppression, echo cancellation, effective interruption detection, and end-of-turn detection, enhancing the overall user experience and ensuring smoother interactions. With these capabilities, developers can create more engaging and lifelike conversational agents that cater to diverse applications.
Description
Seeduplex represents a cutting-edge full-duplex speech large language model that operates on an innovative “listen while speaking” paradigm to facilitate more natural, fluid, and accurately timed voice interactions. Unlike conventional half-duplex systems that switch between listening and responding, it continually processes and comprehends audio from the user, enabling simultaneous listening and speaking while being aware of the surrounding acoustic environment. Its advanced interference suppression capabilities effectively differentiate genuine user input from background distractions such as noise, broadcasts, navigation cues, and overlapping conversations, thereby minimizing incorrect responses and disruptions in intricate scenarios. Furthermore, Seeduplex integrates both speech and semantic features for dynamic endpoint detection, allowing it to discern when a user is contemplating, pausing, correcting themselves, or has completed their statement. This model exhibits the ability to patiently endure reflective silences, provide swift responses immediately after an utterance concludes, and seamlessly cease speaking when interrupted, ensuring a more engaging interaction. Ultimately, the design of Seeduplex aims to enhance user experience by making voice communication feel more intuitive and responsive.
