Knovvu Analytics by SESTEK is an enterprise speech-and-text analytics platform that transcribes and analyzes 100% of customer voice and digital interactions for contact centers.
Clevercast is a SaaS platform for multilingual live streaming and accessibility, aimed at organizations broadcasting events, conferences, webinars, and meetings to global audiences. Incoming audio and video are sent from an encoder to Clevercast, which generates AI closed captions described as having high accuracy, including for streams where multiple languages are spoken. From that speech-to-text source it can produce live subtitles in multiple languages, synthetic AI voice translations that viewers select per language, and on-site scrolling transcripts displayed on screens for event attendees. A web interface lets operators correct the AI transcription in real time, improving the resulting captions and translations, and remote human interpreters can also be added for events with strict quality requirements. Streams are delivered via HLS through a global CDN and can be embedded in Clevercast's player or distributed to platforms such as YouTube. It suits enterprises, international bodies, educational institutions, and media companies that need accessible, language-inclusive live broadcasts rather than a personal meeting note-taker.
