Acoustic Study of the Vowel Formant Frequencies and F0: A Contribution to Catalan Forensic Phonetics

Fundamental frequency and the frequencies of the F1, F2 and F3 formants of all Catalan vowels have been acoustically measured in a reading-speech corpus of 10 speakers. Several phonological aspects such as stress, context and phrasal intonation have been taken into account. The data was processed using statistical tests (MANOVA) and post-hoc comparisons to evaluate the intra-speaker and inter-speaker variation, and significant differences between speakers, place and manner of articulation. Also, most speaker-specific parameters have been identified. In addition, the value of the results for the forensic phonetics is discussed.
