Call transcription

Call transcription takes the audio from a Call recording and writes down what was said as text. Instead of listening to a ten-minute call to find one sentence, you read the transcript or search it for a keyword. Speech-to-text software does the work, usually after the call ends, and saves the result alongside the recording so the two stay linked. Open a call later and you can read it in seconds rather than playing it from the start.

For a call center, transcripts make quality review far faster. A supervisor can scan dozens of calls in the time it once took to play back two, and can search across every call for phrases like a competitor's name, a refund request, or a promise an agent should not have made. Transcription is also the raw material for Voice analytics, which layers sentiment scores, topic detection, and trend tracking on top of the plain text — none of which is possible while the conversation is still locked inside an audio file.

What to keep in mind

Transcription is not perfect. Accents, two people talking over each other, background noise, and a bad connection all hurt accuracy, so treat a transcript as a strong guide rather than a word-for-word legal record. If something truly matters, go back to the original audio. It is worth noting that transcription goes from audio to text, which is the exact opposite direction from TTS (text to speech) (text-to-speech), where written text is turned into spoken audio for things like an automated greeting.

A transcript is still a record of the conversation, so it falls under the same care as the audio. Include transcripts in your Recording retention policy and access rules, and remember they make searching for sensitive data much easier — which is helpful for honest review but means you should guard them just as carefully as the recordings. Used well, transcripts feed coaching and Agent performance reviews so a manager can spot patterns across the whole team without replaying hours of audio one call at a time.
