Do Infants Discriminate Hyper-from Non-Hyperarticulated Speech?
… by the relations of the first (F1) and second formant frequencies (F2) of the vowel. The result showed that there was no discrimination between listening to hyperarticulated and non-hyperarticulated words, indicating that the benefit accrued by exposure to clear speech may require no selective …

Changing her tune : how a transsexual woman claims a new identity through voice
… resonance, volume, speech patterns and formant frequencies also play significant roles in making a realistic feminine sound. There continue to be many unanswered questions about how listeners perceive the voices of transgender women and how best to blend the voices of transwomen into a …

Assessing functional links between speech production and perception in multilingual speakers
… of their produced speech. A change in the formant frequencies of the perceived vowel (induced artificially by altered auditory feedback) can be associated with a change in production to offset the perturbation. This response is termed adaptation. The data in this thesis comes from four …

Prosodically Induced Acoustic Variation in English, Korean, and Hindi
… with vowel duration and the first and second formant frequencies for vowels. Measurements are taken from the speech of six male American English speakers, five male Seoul Korean speakers, and five male Delhi Hindi speakers. Statistical results indicate that the effect of focal accent on …

Hypernasal Speech Analysis via Emperical Mode Decomposition and the Teager-Kasiser Energy Operator
… in the study of speech is the analysis of speech formants, i.e., vocal tract resonances. Traditional acoustical analysis methods of using a linear source model follow the premise that differences between normal and hypernasal speech can be distinguished by shifts or power changes in the formant …

Accent Conversion via Formant-based Spectral Mapping and Pitch Contour Modification
… of accents. Acoustic characteristics such as formant frequencies, fundamental frequency and its variation slope, intensity of speech, and duration of phone were used for accent acoustic analysis. In this dissertation, accent conversion via formants modification and pitch contour manipulation …

Modelling the effects of speech rate variation for automatic speech recognition
… in coarticulation. Centralisation means that the formant frequencies of vowels tend to shift towards the vowel space center while increased coarticulation denotes the tendency of the spectral features of a vowel to shift towards those of its phonemic neighbour. The goal of this work is to …

The phonetic correlates of pharyngealization and pharyngealization spread patterns in Cairene Arabic an acoustic and real-time magnetic resonance imaging study
… configuration is a lowering of the second formant frequency in surrounding vowels. The extent of the modification in the formant frequency is determined by the length and quality of the vowel. This study uses real-time magnetic resonance imaging (rtMRI) to investigate the acoustic and …

Computational measures of linguistic variation: a study of Arabic varieties
… based on the values of the first and second formant frequencies, MSA is not included at this level. The results of the measures of linguistic variation developed in this study confirm two observations about the communication between speakers of the Arabic varieties and provide an answer for …

Síntesis multilocutor aplicando técnicas de conversión de hablante
… propuestas de sintetizador: 1. Sintetizador de formantes que concatena unidades parametrizadas. En este caso los parámetros que se utilizan para la síntesis son los cinco primeros formantes y cuatro parámetros de fuente glotal del modelo LF (Liljencrants & Fant). 2. El segundo de los …

Investigating sources of phonological rarity and instability: a study of the palatal lateral approximant in Brazilian Portuguese
… of the tongue body, duration of the phone, or formant frequencies. The perception study included in the appendix finds that while both native and non-native speakers of BP distinguish between the palatal lateral and palatalized lateral at chance level, native speakers of BP perform better than …
