A NOVEL APPROACH TO STUTTERED SPEECH CORRECTION
Abstract: Stuttered speech is
a dysfluency rich speech, more prevalent in males than females. It has been
associated with insufficient air pressure or poor articulation, even though the
root causes are more complex. The primary features include prolonged speech and
repetitive speech, while some of its secondary features include, anxiety, fear,
and shame. This study used LPC analysis and synthesis algorithms to reconstruct
the stuttered speech. The results were evaluated using cepstral distance,
Itakura-Saito distance, mean square error, and likelihood ratio. These measures
implied perfect speech reconstruction quality. ASR was used for further
testing, and the results showed that all the reconstructed speech samples were
perfectly recognized while only three samples of the original speech were
perfectly recognized.
