Several recent studies by Lehiste have reported that changes in fundamental frequency (FO) can serve as a cue to perceived vowel length and, furthermore, that the perceived lengthening of the vowel can influence perception of the voicing feature of stop consonants in syllable-final position. In Experiment 1, we replicated Lehiste's basic results for stop consonants in final position. Experiment 2 extended these results to postvocalic fricatives. The final consonant in syllables of intermediate vowel duration was more often perceived as voiced when FO was falling than when FO was monotone. In Experiment 3, we examined the FO contours produced by eight talkers before postvocalic stop consonants and fricatives in natural speech for minimal pairs of words differing in voicing. The amount of change of FO over the vowel was no greater before voiced than voiceless consonants, suggesting that the earlier perceptual effects cannot be explained by appealing to regularities observed in the production of FO contours in vowels preceding postvocalic consonants.Recently, several investigators have observed that perceived vowel duration can be influenced by the fundamental frequency (FO) contour of the vowel (e.g., Lehiste, 1976; Pisoni, Note 1; Wang, Lehiste, Chang, & Darnovsky, Note 2). In particular, vowels with a changing FO were found to be perceived as longer than vowels with a monotone PO. The direction of change seems to have little influence on this effectvowels with rising FOs and vowels with falling FOs were both perceived as longer than vowels with level FOs (Lehiste, 1976).Variations in vowel duration are known to have at least two important effects on phoneme identification. First, vowel duration systematically influences the identification of the vowel itself (e.g., Stevens, 1959). Two vowels with identical formant frequencies but different durations are frequently identified as different vowels. This effect is particularly strong for the IE.! (short vowel)-Iael (long vowel) distinction. Second, vowel duration has been shown to affect the perception of voicing of a following consonant (e.g., Denes, 1954). A consonant following a long vowel is more likely to be perceived as voiced This paper is a substantially expanded version of a paper delivered by the first author at the 97th meeting of the Acoustical Society of America, June 12·17, 1979, Cambridge, Massachusetts.

Because the FO contour affects perceived vowel duration, it seems reasonable to suppose that the FO contour over a syllable can also serve as a phonemic cue. In particular, placing a contour on the FO ...

Abstract-Joint fundamental frequency and model order estimation is an important problem in several applications. In this paper, a default estimation algorithm based on a minimum of prior information is presented. The algorithm is developed in a Bayesian framework, and it can be applied to both real-and complex-valued discrete-time signals which may have missing samples or may have been sampled at a non-uniform sampling frequency. The observation model and prior distributions corresponding to the prior information are derived in a consistent fashion using maximum entropy and invariance arguments. Moreover, several approximations of the posterior distributions on the fundamental frequency and the model order are derived, and one of the state-of-the-art joint fundamental frequency and model order estimators is demonstrated to be a special case of one of these approximations. The performance of the approximations are evaluated in a small-scale simulation study on both synthetic and real world signals. The simulations indicate that the proposed algorithm yields more accurate results than previous algorithms. The simulation code is available online.

“…Mrate incorporates multiple estimators, a technique that has been shown to be beneficial for many aspects of speech analysis, such as the parallel pitch detection approach developed by Gold and Rabiner 30 years ago [1]. As in that case, using multiple estimators significantly improves the error variance.…”

We report progress in the development of a measure of speaking rate that is computed from the acoustic signal. The newest form of our analysis incorporates multiple estimates of rate; besides the spectral moment for a full-band energy envelope that we have previously reported, we also used pointwise correlation between pairs of compressed sub-band energy envelopes. The complete measure, called mrate, has been compared to a reference syllable rate derived from a manually transcribed subset of the Switchboard database. The correlation with transcribed syllable rate is significantly higher than our earlier measure; estimates are typically within 1-2 syllables/second of the reference syllable rate. We conclude by assessing the use of mrate as a detector for rapid speech.
