Controlled voice quality modifications
Within-speaker variability, which results from the plasticity of speech production, is an inherent feature of speaker comparison. This study examines targeted modifications of voice quality, both phonatory and articulatory, in Czech. Fifteen speakers were instructed to read a text in 15 different versions (e.g. palatalised voice, denasalised voice, breathy phonation, or a combination of open jaw and creaky voice). Acoustic analyses revealed that …
Intra- and inter-speaker variability of vowel space using three different formant extraction methods
Individual speakers’ voices display various unique patterns, one of the most prominent of which is vowel articulation. This study focuses on vowel space properties of 15 Czech speakers in read and spontaneous speech, comparing outputs of three formant extraction methods, measuring formants: (1) in the vowels’ temporal midpoints, (2) as their mean from the vowels’ middle thirds, and (3) in the vowels’ articulatory targets. The results show extensi…
The impact of mismatched recordings on an automatic-speaker-recognition system and human listeners
The so-called ‘mismatch’ is a factor which experts in the forensic voice comparison field encounter regularly. Therefore, we decided to explore to what extent the automatic-speaker-recognition system’s and the earwitness’ ability to identify speakers is influenced when recordings are acquired in different languages and at different times. 100 voices in a database of 300 recordings (100 speakers recorded in three mutually mismatched sessions) were…
