WebOct 18, 2024 · In this work, we compare from-scratch sequence-level cross-entropy (full-sum) training of Hidden Markov Model (HMM) and Connectionist Temporal Classification (CTC) topologies for automatic speech recognition (ASR). Besides accuracy, we further analyze their capability for generating high-quality time alignment between the speech … WebCTC(y x⌊L/2⌋). (13) Then we note that the sub-model representation x⌊L/2⌋ is naturally obtained when we compute the full model. Thus, after computing the CTC loss of the full model, we can compute the CTC loss of the sub-model with a very small overhead. The proposed training objective is the weighted sum of the two losses: L :=(1−w)L ...

It involves recognizing the words spoken in an audio recording and transcribing them into a written format. The goal is to accurately transcribe the speech in real-time or from recorded audio, taking into account factors such as accents, speaking speed, and background noise.
