About

Azure Voice Live API is a fully managed solution for building low-latency, high-quality speech-to-speech agents through one unified interface. It combines speech recognition, generative AI, and text-to-speech, allowing developers to send audio input and receive audio output, synchronized avatar visuals, and action triggers without manually orchestrating separate backend components or deploying the underlying models. It supports more than 140 speech-to-text locales and over 600 standard voices across 150+ text-to-speech locales, with options for phrase lists, custom speech, custom voices, and brand-aligned avatars. Developers can choose among multiple generative AI models, including GPT-Realtime, GPT-5, GPT-4.1, GPT-4o, Phi, and compatible bring-your-own models, depending on the intelligence, speed, and latency required. Advanced conversational features include noise suppression, echo cancellation, robust interruption detection, and end-of-turn detection.

About

Rubidium enables leading companies to embed voice commands and text to speech in their products. Voice Trigger is an “always on” engine that continuously listens and wakes up when you say the proper “magic word”. Voice Trigger identification uses a sophisticated miniature footprint Automatic Speech Recognition (ASR) engine to run in the background and distinguish between the trigger phrase and the rest of the speech, sounds and noise. Automated Speech Recognition (ASR) easily and safely controls any set of functions through voice commands. For example: call acceptance and rejection, device setup and installation procedure (pairing, calibration, interconnection, etc.), voice dialing, music streaming control and music selection. Rubidium technology is now embedded in over 50 million consumer products with customers and partners including leading global brands such as RIM (Blackberry), GN Netcom (Jabra), Panasonic, Uniden, CSR, Mattel, General Motors, Electrolux and many others.
