Speech Recognition Algorithms

How do speech recognition algorithms utilize acoustic models to analyze audio input?

Speech recognition algorithms utilize acoustic models by breaking down audio input into smaller segments called phonemes, which are the basic units of sound in a language. These acoustic models analyze the characteristics of each phoneme, such as frequency and duration, to match them with known patterns in the model. By comparing these patterns to the audio input, the algorithm can accurately transcribe spoken words based on the acoustic features present in the input.
