Abstract :
The esophageal voice that people who have suffered a total laryngectomy use for their communication, can be characterized with the typical voice evaluation parameters such as the pitch, jitter, shimmer and SNR, that reflect its low quality. In the present abstract, an algorithm specifically designed for esophageal voices that increases its SNR from a minimum of 1,8dB to a maximum of 7,1dB is exposed.
