Miscellaneous noises

Miscellaneous noises in recorded audio can come from various sources such as TVs, music, nearby people, and so on. Voci employs noise detection techniques to eliminate noises from the signal before sending the audio for further processing.

The noise removal process is not perfect. Audio sources that share the same frequency range as speech are a bit more challenging. In a call center environment, it is not uncommon for nearby call center agents to be recorded. If non-speech elements remain in the audio at transcription time, the overall transcription accuracy will be negatively affected.

The following best practices ensure minimal noise is recorded:

  • Use headsets with high-quality near-field microphones

  • Make the recording workspace as quiet as possible

  • Use high quality telephony and recording equipment
