What does an acoustic model do in speech recognition?

An acoustic model is used in automatic speech recognition to represent the relationship between an audio signal and the phonemes or other linguistic units that make up speech. The model is learned from a set of audio recordings and their corresponding transcripts.

What is acoustic event detection?

Devices that are always listening for acoustic events are ready to alert you at any sign of trouble so you can address the problem immediately - even if you're away.

What is acoustic signal in speech?

Acoustic properties of speech signals

The fundamental frequency of a speech signal or its absence carries a lot of information. Per definition, voiced and unvoiced phonemes, respectively, are those with or without an oscillation in the vocal folds.
