Aculab Cloud vs Recognition Technologies Speaker Recognition

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

Recognition Technologies Speaker Recognition is a language- and text-independent voice biometrics system for identifying and verifying speakers. A person may enroll in one language and be identified or verified in another. The engine also supports classification, detection, tracking and segmentation. Identification can use open-set or closed-set approaches; closed-set identification can return the nearest enrolled voice even if the speaker is not in the database. The maker describes verification enrollment as about 30 seconds of speech, followed by a few seconds when the speaker returns. Interfaces include a C++ SDK/API, command line, web service, Android and iOS; the engine can also be used as a module of the maker’s IVR system. Deployment options include embedded, server-based, standalone, hosting at Recognition Technologies or hosting at the customer’s facilities. The product page lists Linux, Apple Macintosh OS X and Windows support. Its telephony version supports speaker verification and identification for telephone authentication and access-level control. Pricing is on request, and an evaluation account for the hosted version may be available to interested organizations.
