Advanced Topic 48 of 49 Graphics, Vision & Media
Speech Recognition
Converting spoken audio into text.
How it works
ASR converts audio to text: features (MFCC, spectrograms) feed acoustic models (now end-to-end transformers like Whisper) with language models; word error rate (WER) measures accuracy.
Where it is used
Assistants, captions.
Common pitfall
Accents, noise and domain vocabulary hurt accuracy.
Where it fits in the course
Speech Recognition is topic 48 of 49 in Graphics, Vision & Media, rated Advanced. It follows Video Codecs. The next topic is Neural Rendering.
