“…The score for phonated voweIs, which provided Fo height information, was 45%. Similar scores emerged in a study by LaRiviere (1975) using whispered and phonated vowels of 1250 msec duration (22% and 40% correct identification, respectively).…”

Four speaker identification tests were conducted using five female speakers known to the listeners. Starting from acoustic recordings of reiterant "ma" syllables, the perceptual importance of the following three factors was investigated: F0 height, F0 contour, and speech rhythm. For speakers with typically low or high voices F0 height turned out to be a highly relevant cue in speaker identification. For all speakers F0 contour was of secondary importance, whereas speech rhythm had a small but consistent influence on recognition rates. It could be inferred that remaining factors alone (mainly global spectral information) would yield recognition scores of approximately 50%. Consistent with previous investigations, the relevance of perceptual cues in the recognition of familiar voices was shown to be not hierarchically fixed, but to depend on speaker-specific voice characteristics.

“…Earlier research has sought to determine what factors could potentially be relevant for the judgement of voices. Several studies chose phonated versus whispered speech material in order to investigate the contribution of speaking fundamental frequency (FO) and the filtering function of the vocal tract (e.g., Bennett & Montero-Diaz, 1982;LaRiviere, 1974LaRiviere, , 1975Lass et al, 1976Lass et al, , 1980dLinville & Fisher, 1985). Coleman (1976) used a laryngeal vibrator simulating typically male/female FO for speakers of both sexes in order to compare the contributions of the two above-mentioned factors.…”

Acoustic Parameters in Speaker Height and Weight Identification: Sex-Specific Behaviour

This study examines the ability of listeners to judge speaker height and weight from speech samples. Although previous investigations indicate that listeners are consistent in estimating body characteristics, it is not known which speech signal parameters are being used by the listeners for such estimates. Therefore, a series of listening tests was carried out in which male and female listeners judged the height and weight from male and female speakers reading isolated words and two text paragraphs. Both speaker sex and listener sex turned out to be important factors: Significant correlations between estimated height/weight and actual height/weight were found only for male speakers. The majority of these estimates came from the male listeners. Neither male nor female listeners, however, were able to estimate female speaker height or weight. Regression analysis involving F0, formant frequencies, energy below 1 kHz, and speech rate showed no significant correlations between these parameters and actually measured speaker height and weight, the only exception being a significant correlation between male speaker weight and speech rate. Furthermore, regression data suggested that the listeners (correctly) used speech rate information in judging male speaker weight, whereas low F0 and formant frequency values (wrongly) were taken to indicate large speaker body dimensions.

“…Many of these investigators focused on suprasegmental elements such as SFF, i.e., speaking fundamental frequency 4,31 , voice quality 14,25 (long term specta), temporal speech features 29,32 and related. Also researched for SI purposes were vowels 40,46 , (especially vowel formats), fricatives 53 , nasality and related segmentals 45,47 . The observed relationships have been revisited again and again over the years; they have tended to confirm and expand Steven's 57 early review of the segmental and suprasegmental elements that can be employed in the speaker-identification process.…”

Linguistics and phonetics overlap in many areas. The essay to follow reviews some of the problems experienced by phoneticians in one of these regions. It may provide some insight for linguists when they are confronted by barriers in their own field. The present example involves individuals who are attempting to identify speakers from voice analysis. The fundamental challenge they face is, of course, caused by the thousands of variables associated with that task. Included here are differences among speakers' gender, age, size, physiology, language, dialect, psychological/health states, background/education, reason for speaking, situation, environment, configuration of the acoustic channel --plus many others. Many formal assessment procedures --both aural-perceptual ones conducted by humans or machine/computer based systems --have been proposed and/or used for the cited analyses. Unfortunately, however, few have enjoyed particularly high levels of success. Worse yet, reasonable progress has suffered from external impedances; the report to follow will outline some of them. Among the problems considered are: 1) competition (verification vs. identification, from voiceprints), 2) concept disputes 3) the continued undervaluation of relevant evidence and 4) markedly dissimilar philosophies of professionals from different disciplines. A response in the form of a short review of the data and concepts which clearly support the possibility of robust speaker identification is presented. Also included are suggestions as to how to enhance the effectiveness of disciplines such as ours.
