Speech Analysis Systems

Abstract

Performance characteristics are reviewed for seven systems marketed for acoustic speech analysis: CSpeech, CSRE, ILS-PC, Kay Elemetrics model 5500 Sona-Graph, MacSpeech Lab II, MSL, and Signalyze. The characteristics reviewed include system components, basic capabilities (signal acquisition, waveform operations, analysis, and other functions), documentation, user interface, data formats and journaling, speed and precision of spectral analysis, and speed and precision of fundamental frequency analysis. Basic capabilities are also tabulated for three recently introduced systems: the Sensimetrics SpeechStation, the Kay Elemetrics Computerized Speech Lab (CSL), and the LSI Speech Workstation. In addition to the capability and performance summaries, this article offers suggestions for continued development of speech analysis systems, particularly in data exchange, journaling, display features, spectral analysis, and fundamental frequency analysis.

A software tool for auditory and speech perception experimentation

“…Some other programs are available for this type of research. For instance, Read, Buder, and Kent (1992), in their review of seven computer systems for speech research, mention some systems (e.g., Computer Speech Lab, CSL, and Computerized Speech Research Environment, CSRE 4.2) that offer stimulus presentation facilities. Other general purpose programs (e.g., Micro Experimental Laboratory, MEL, and Mathematica) can also be used for stimulus presentation.…”

Assessing the contribution of instructional technology in the teaching of pronunciation

“…The space here is too limited for a detailed comparison with other systems for speech analysis, as it has been done elsewhere [9,11]. In my personal experience, CECIL has shown to be the most attractive system for working with the acoustics of speech.…”

“…Some students considered to sing "double-stressed" or "double-accented" these words on the stressed and poststressed syllables: *[pre.si.dén.té]. Perhaps this can be explained by a common tendency in Spanish to strengthen postonic syllables in prepausal position, as discussed in [11]. Figure 1 illustrates one of the several acoustic correlates of singing-like pronunciation.…”

“…In my personal experience, CECIL has shown to be the most attractive system for working with the acoustics of speech. Nevertheless, my main reasons to work with CECIL and not for example with another excellent system like CSRE [11], are its price, adaptability, and its specific design for prosodic analysis. CECIL can create numerical files exportable and convertible to data processors for graphic, statistical and other numerical analyses.…”

Fundamentalmente, o modelo postula que o sinal de fala que é radiado pelos lábios 21 representa e contém características da fonte (glote) e também do filtro (trato vocal), ou seja, o som produzido pela vibração das pregas vocais é modificado ao passar pelas características específicas do filtro vocal (ressonância) (FANT, 1970;1973;KENT e READ, 1992;KENT, 1993KENT, , 1997. O modelo proposto por FANT foi adotado por outros autores como ISHIZAHA, FLANAGAN, 1972e DAVIS, 1979 Este modelo matemático pressupõe três principais sub-sistemas acústicos para a produção da voz: de conformação do pulso glótico; de caracterização do trato vocal e de radiação labial (KENT, 1993(KENT, ,1997.…”
