The company serves developers building voice applications as well as enterprise organizations, with solutions highlighted for contact centers, restaurants, pharma, medical, and government, along with transcription, conversational AI, and speech analytics use cases. The website states that its platform has processed more than 200,000 years of audio, supports over 650,000 developers and more than 5,000 organizations, and offers 99.99% enterprise-grade reliability. It also says its STT and TTS run on a shared runtime, so teams can use both under one platform.
