This study investigates high vowel laxing in the Louisiana French of the Lafourche Basin. Unlike Canadian French, in which the high vowels /i, y, u/ are traditionally described as undergoing laxing (to [I, Y, U]) in word-final syllables closed by any consonant other than a voiced fricative (see Poliquin 2006), Oukada (1977) states that in the Louisiana French of Lafourche Parish, any coda consonant will trigger high vowel laxing of /i/; he excludes both /y/ and /u/ from his discussion of high vowel laxing. The current study analyzes tokens of /i, y, u/ from pre-recorded interviews with three older male speakers from Terrebonne Parish. We measured the first and second formants and duration for high vowel tokens produced in four phonetic environments, crossing syllable type (open vs. closed) by consonant type (voiced fricative vs. any consonant other than a voiced fricative). Results of the acoustic analysis show optional laxing for /i/ and /y/ and corroborate the finding that high vowels undergo laxing in word-final closed syllables, regardless of consonant type. Data for /u/ show that the results vary widely by speaker, with the dominant pattern (shown by two out of three speakers) that of lowering and backing in the vowel space of closed syllable tokens. Duration data prove inconclusive, likely due to the effects of stress. The formant data published here constitute the first acoustic description of high vowels for any variety of Louisiana French and lay the groundwork for future study on these endangered varieties.
Ph@ttSessionz and Deutsch heute are two large German speech databases. They were created for different purposes: Ph@ttSessionz to test Internet-based recordings and to adapt speech recognizers to the voices of adolescent speakers, Deutsch heute to document regional variation of German. The databases differ in their recording technique, the selection of recording locations and speakers, elicitation mode, and data processing.
In this paper, we outline how the recordings were performed, how the data was processed and annotated, and how the two databases were imported into a single relational database system. We present acoustical measurements on the digit items of both databases. Our results confirm that the elicitation technique affects the speech produced, that f0 is quite comparable despite different recording procedures, and that large speech technology databases with suitable metadata may well be used for the analysis of regional variation of speech.
