HMM-based speech recognition/synthesis: state representation of monophones and triphones
In literature, a monophone is represented with 3 states.
When doing context dependent clustering, 3 states are used to represent a triphone.
Why is the triphone represented with 3 states and not 5? …

Effect of redundant training data in HMM-based speech recognizer/synthesizer?
Then the training (for a monophone) is done with:
$$\lambda_{max}^\theta = \text{arg} \max_\lambda p(\bf{O}|\lambda) $$
where $\bf{O}$ is the observation sequence and $\lambda$ is the HMM model. …

Why are the observation features (namely MFCCs) of an HMM-based recognition/synthesis system modeled by a Gaussian distribution?
Even the state duration is modeled by a Gaussian in this paper:
