To get the most from Voci's Automatic Speech Recognition (ASR) solutions, it helps to understand the variables that affect transcription accuracy. Audio is the primary input to an ASR system; therefore, the quality of the audio files have a significant impact on transcription accuracy.

In general, the best audio recording practices are to:

• Use dual-channel (stereo) audio.

• Use a sampling rate of 8kHz.

• Use high quality telephony and recording equipment.

• Minimize surrounding noise in environments where audio is recorded.

• Record high quality audio with codecs that are optimized for speech.

• Avoid lossy transcoding and compression, as with audio in MP3 format

The pages in this section elaborate on these audio recording practices.
