Fifth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2007)
A multi-purpose software tool (BioVoice) is
presented, capable of performing automatic analysis of a
large range of voice signal, no manual setting being
required to the user. This makes the tool feasible for
application by non-expert users in several fields, ranging
from high-pitched new-born cries, to adult healthy
singing vocalizations and to irregular, pathological voice
signals. Main voice characteristics (fundamental
frequency and formants) are evaluated and tracked by
means of robust analysis techniques that can handle the
above mentioned wide range of signals, as internal
settings for optimal frame length, frequency range of
analysis and plots are automatically adjusted.
Specific parameters are evaluated according to the kind of signal under study, and displayed with suitable plots and tables.
In this paper, the method is applied to patient affected by laryngeal hemiplegia that underwent lipofilling treatment to recover phonatory capabilities.
Index Terms. multi-purpose voice analysis tool, robust parameter estimation, laryngeal hemiplegia.
