What SyncWords is
SyncWords is a cloud platform for live and on-demand AI captioning, subtitling, and dubbing. SyncWords Live produces same-language captions, translated subtitle tracks, and Vocalics dubbed audio from live sources, accepting SRT, RTMP, HLS, or CMAF media. Its Live API supports programmatic control, scheduling, webhooks, and multiple language outputs per call. Services can use ASR dictionaries, translation glossaries, and pronunciation rules. Named integrations include AWS Elemental, Zoom, Microsoft Teams, Adobe Connect, YouTube Live, LinkedIn Live, Vimeo, Brightcove, Dacast, and PheedLoop. The platform supports 100 languages, subtitle translation, AI dubbing, voice cloning, review workflows, and API access. SyncWords identifies creators, event organizers, enterprises, broadcasters, OTT platforms, streaming vendors, houses of worship, educational institutions, and government organizations among its audiences. The enterprise solution states that it uses encryption in transit and at rest and HIPAA- and FERPA-ready facilities. There is no free plan, though prospective customers can request a trial session. Hours are billed per language and per output, so each output uses its own hours.
