What is Signal-to-Noise Ratio (SNR)?
SNR (Signal-to-Noise Ratio) is the ratio of desired signal power to background noise power, typically expressed in decibels (dB). Higher SNR means a cleaner signal; low SNR means noise dominates and seems "close" to the speech.
What is an example of Signal-to-Noise Ratio (SNR)?
A speaker close to a studio microphone in a quiet room might have an SNR of 40 dB or more. A caller on a mobile phone walking through a busy street might have an SNR of 5 dB or less, where most modern ASR start to struggle.
How does ai-coustics handle different Signal-to-Noise Ratios?
Low-SNR audio is exactly where our Quail family delivers the most value. By suppressing noise and preserving speech structure, Quail effectively lifts the SNR of the signal reaching ASR, reducing Word Error Rate in the conditions where voice agents otherwise break down.
