Microsoft Launches Live Interpreter API for Real-Time Multilingual Speech Translation
September 15, 2025
The Live Interpreter API enables real-time, multilingual communication, supporting seamless language switching during conversations, which is ideal for applications like contact centers, online meetings, classrooms, and social streaming.
It can be integrated into various applications, allowing users to switch languages effortlessly during conversations, enhancing global communication.
Microsoft has announced the public preview of its Live Interpreter API, a new feature within Azure Speech Translation designed for real-time multilingual speech translation.
This API is built on Azure Speech Translation and offers continuous language detection, extensive language coverage with 76 input languages and 143 locales, and low-latency translation that rivals human interpreters.
A notable feature of the API is its ability to preserve a user’s personal voice, including style, tone, intonation, and pacing, with enterprise-grade consent controls ensuring privacy and security.
Developers can access a QuickStart Guide to easily integrate the API into apps or websites, while end users will benefit indirectly through these platforms.
Microsoft has partnered with Anker Innovations to demonstrate practical uses of the API, focusing on improving audiovisual experiences in real-world scenarios.
