Best Practices
This document contains recommendations on how to provide speech data to the various SoapBox speech solutions. These guidelines are designed for greater efficiency and accuracy as well as reasonable response times from the service. Use of a SoapBox speech solution works best when data sent to the service is within the parameters described in this document.
For optimal results... | Avoid... | |
|---|---|---|
Sampling Rate | Capture audio with a minimum sampling rate of 16,000 Hz. | Lower sampling rates may reduce accuracy. Always avoid re-sampling. |
Encoding | Use a lossless codec to record and transmit audio. | Lossy encoding |
Recording Environment | Our technology is designed to ignore background voices and noise without additional noise-canceling. However, for optimal results, position the microphone as close to the user as possible, particularly when background noise is present. | Excessive background noise and echoes may reduce accuracy, especially if a lossy codec is also used. In cases of poor audio quality, your recognition request can take significantly longer to process |
