Measuring of a software processing speed – what is the FtRT (Faster than Real Time)

…in our example is 36 seconds. After stripping silence, it gets 14 seconds – this means that original audio contains 38% of net speech and 62% of silence. Phonexia speech technologies analyze the entire recording, but pick only the speech segments for AI processing, i.e. the absolute processing time will be practically the same… Creating voiceprint by Speaker Identification took:…

Implemented speech technologies:…

Speaker change on enrollments

…following JSON: { “speaker_change_detection”: “enable” } Once enabled, a voiceprint can be enrolled from a stream via endpoint /api/v2/enroll. Please note that the voiceprint created from a stream is checked for the number of speakers only after the stream has ended. If there is more than 1 speaker detected in the voice, error message is produced when using /api/v2/verify endpoint:…
