Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

Area of Science:

Speech science
Biomedical engineering
Maxillofacial surgery

Background:

Subjective speech evaluation is crucial for maxillofacial rehabilitation.
Previous automatic speech intelligibility test systems using monosyllables had limitations in detecting mild speech disorders in maxillectomy patients.

Purpose of the Study:

To remodel an automatic speech intelligibility test system using sentences as stimuli to overcome the limitations of previous monosyllable-based systems.
To evaluate the effectiveness of the remodeled system in assessing the speech of normal adults and maxillectomy patients.

Main Methods:

The speech of 10 normal adults and 13 maxillectomy patients was assessed using the remodeled automatic conversation intelligibility test system with sentence stimuli.
Patient speech was evaluated with and without prostheses, and results were compared to perceptual intelligibility measures.

Main Results:

The automated system demonstrated consistent results for normal subjects across multiple trials.
Maxillectomy patients showed significantly improved speech intelligibility scores when using prostheses.
Strong correlations were found between automated test results and perceptual intelligibility assessments for patients with and without prostheses.

Conclusions:

The enhanced automatic conversation intelligibility test system, utilizing sentences, is effective for evaluating speech in maxillectomy patients.
This system offers a sensitive and reliable tool for assessing speech disorders in maxillofacial rehabilitation.
