WebDec 1, 2024 · Dec 1, 2024. Deep Learning has changed the game in Automatic Speech Recognition with the introduction of end-to-end models. These models take in audio, and directly output transcriptions. Two of the most popular end-to-end models today are Deep Speech by Baidu, and Listen Attend Spell (LAS) by Google. Both Deep Speech and … CTC is an algorithm used to train deep neural networks in speech recognition, handwriting recognition and other sequence problems. CTC is used when we don’t know how the input aligns with the output (how the characters in the transcript align to the audio). The model we create is similar to DeepSpeech2.
