Noise Suppression
Audio processing technology that filters out background noise from the microphone input, improving speech recognition accuracy in noisy environments.
Understanding Noise Suppression
Noise suppression (also called noise cancellation or noise reduction) uses digital signal processing to reduce or eliminate unwanted background sounds from an audio stream. In live translation settings, common noise sources include audience chatter, HVAC systems, musical instruments, and ambient event sounds. By filtering out this noise, the speech recognition engine receives a cleaner audio signal, resulting in more accurate transcription and better translation quality.
How Selah Translate Uses Noise Suppression
Selah Translate includes a noise suppression toggle in the Translation Studio. When enabled, background noise is filtered from the audio input before speech recognition, improving transcription accuracy. This is particularly useful in churches during worship music, conference halls with ambient noise, and any venue where the speaker isn't in a perfectly quiet environment.
