The link in the article didn't work for me; I'm referring to: https://research.microsoft.com/apps/pubs/default.aspx?id=153169 https://research.microsoft.com/apps/pubs/default.aspx?id=153...
- gdahl 15y agoNo, the HMM is not replaced in that work. The GMM is replaced, as you surmise. There are three problems with standard ASR: HMMs, GMMs, and n-gram language models. The GMM is the easiest to remove. Keeping the HMM allows simple, efficient decoding algorithms.
