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
TekIVR (Based on RFC3261) is an Interactive Voice System (IVR), a SIP, for Windows. TekIVR can be used on Microsoft Windows Vista, Windows 7/8/10/11, and Windows 2008-2022 servers. TekIVR's user interface is simple and easy to use. You can create your own IVR scenario using built-in scenario editor. You can choose your own audio files for use in an IVR scenario. TekIVR can also read out texts using TTS (Text to Speech) engine and recognize input via speech recognition. When defining prompts, Speech Synthesis Markup Language can be used. TekIVR supports SAPI and Google Cloud Speech API, Azure Cognitive Services, and MRCPv2 to support TTS and ASR functions. It supports ITU G.711 A.Mu Law, G.722 codecs, and UPnP to support NAT traversal. TekIVR can be used as a proxy between MRCP v2 based applications servers and SAPI Azure, Google Speech based speech engine. MRCP v2 based servers can use TekIVR to access SAPI, Azure, and Google Speech based TTS/ASR services.
