This paper concerns the relationships amongst acoustic phonetic features of speech signals, perceived vocal effort, and speech clarity. It is presented from a statistical analysis of a good number of subjective testing on an anechoic speech corpus with 5 different vocal efforts, namely hushed, normal, raised, loud, and shouted, with an aim to map objective acoustic phonetic features onto subjec...

In order to better model pronunciation variations, we present in this paper a method to build a lexicon whose content changes dynamically with the input speech. To achieve this goal, we proceeded in two steps. In the first step, a static augmented lexicon is created by adding new phone transcriptions to a basic lexicon. These new variants are derived from phonetic features that are automaticall...

By mapping acoustic parameters onto phonetic features, it is possible to explicitly address the linguistic information in the signal. For the experiments presented in this paper, we mapped cepstral parameters onto two sets of phonetic features, one based on the IPA chart and the other on SPE. As a result, the phoneme identification rates in a hidden Markov modelling framework increase from 15.6...

language users benefit from special phonetic tools in order to communicate linguistic information as well as different emotional aspects and paralinguistic information through daily conversation. having functions in conveying semantic information to listeners, prosodic features form the essential part of linguistic behavour, manipulating  them potentially can play an important role in transmitt...

this paper examines the stylistics of the ‘arafa supplication in terms of their acoustic and phonetic levels. this supplication has a unique and consistent texture. the acoustic features of the words and sentences and the repetition of some sounds, words and phrases and acoustic syllables, as well as literary devices such as rhyme and paronomasia tend to increase the rhythm of speech. in fact, ...

The quality of corpus-based text-to-speech (TTS) systems depends strongly on the consistency of boundary placements during phonetic alignments. Expert human transcribers use visually represented acoustic cues in order to consistently place boundaries at phonetic transitions according to a set of conventions. We present some features commonly (and informally) used as aid when performing manual s...

We report an investigation of the production of real and non-words in two normal speaker groups. Group 1 consists of 6 young females (mean age 26 years) and Group 2 consists of 5 older females (mean age 54 years). The speech material used in the study consisted of two repetitions of 10 real, 10 pseudo-real and 10 non-words. The results from both repetitions for measures of response latency, utt...

It is generally assumed that the phonetic categories of speech are not indissoluble wholes, but rather can be characterized in terms of a bundle of phonetic or distinctive features. These features may be defined in terms of either acoustic or articulatory attributes of the speech signal. However, it is also the case that at least from an acoustic or perceptual point of view, each of these phone...
