acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

It could be said that Acoustics forms a bridge between speech production and speech perception, and as such it lies at the intersection of several speech communication related fields. The field of Speech and Hearing Sciences, for example, deals with speech production and speech perception. Speech Pathology also relates crucially to Acoustics. In addition, the linguistic fields of Phonetics and ...

This paper presents a quantitative analysis of the relation between speech acoustics and the 2D video signal of the facial motion that occurs simultaneously. 2D facial motion is acquired using an ordinary video camera: after digitizing a video sequence, a search algorithm is used for tracking markers painted on the speaker’s face. Facial motion is represented by the 2D marker trajectories; wher...

Hidden Markov models (HMMs) of speech acoustics are the current state-of-the-art in speech recognition, but these models bear little resemblance to the processes underlying speech production (Lee, 1989). In this respect, using an HMM to model speech acoustics is like using a Gaussian distribution to model data generated by a Poisson process – to the extent that the model is not an accurate repr...

Speech recognition should be as an eyes-free and handsfree interface. To realise this technology, we need to clarify acoustics in a helmet and determine how much highlevel riding noise affects captured speech data. This paper describes the acoustics in a helmet and transfer functions of the microphone position. We constructed a data collection system and collected the speech data of motorbike r...

This paper examines the degrees of correlation among vocal-tract and facial movement data and the speech acoustics. Multilinear techniques are applied to support the claims that facial motion during speech is largely a byproduct of producing the speech acoustics and further that the spectral envelope of the speech acoustics can be better estimated by the 3D motion of the face than by the midsag...

This paper presents a robust speech recognition method based on the HMM composition for the noisy room acoustics distorted speech. The method realizes an improved user interface such as the user is not encumbered by microphone equipments. The proposed HMM composition is obtained by naturally extending the HMM composition method of an additive noise to that of the convolutional room acoustics di...
