Audio and text are not the same asset
Call recording
A recording is the audio of a conversation stored against the record. It is complete and unambiguous: tone, hesitation, interruption and exactly who said what. Its weakness is that reviewing it costs the same time as the call itself, and audio cannot be searched.
Call transcription
A transcription is text generated from that audio. It is skimmable, searchable and can feed summaries, keyword alerts and coaching reviews. Its weakness is that it is a derived artefact: accents, background noise, crosstalk and mixed-language conversation all reduce accuracy.
