About

Aculab Cloud provides APIs for building business applications that handle voice and video calls, messaging, and inbound or outbound fax. It supports calls to phone numbers and SIP addresses, and WebRTC can add live calling to a web page. Listed capabilities include speech recognition, translation, text-to-speech, live speaker detection, voice biometrics, SMS, MMS, and fax. The REST API works with Python, C#, VB, Java, PHP, or other scripting languages; REST applications run on a web server you host. UAS applications run in a User Application Server installed on your platform and support Python, C#, VB, F#, and C++. Speech recognition uses Google Speech-to-Text; text-to-speech supports Amazon Polly and Cepstral. The service runs on AWS, uses HTTPS for web services and SSL by default for UAS connections, and lets customers encrypt media files with runtime-supplied keys. Accounts are assigned to a region: Europe, USA-East, or USA-West (beta). The free Trial includes $10 credit for one month. Production is pay-as-you-go, with rates in the Cloud Console; Premium usage is invoiced.
