We introduce a clinical voice evaluation system. The system is primarily intended as a versatile voice assesment instrument at voice clinics. It also provides a useful research tool for speech scientists, otolaryngologists and speech therapists. The system includes a Windows application with associated dynamic link libraries, DSP programs, and a specific DSP system and interface hardware. The system needs a PC and Microsoft (R) Windows (TM) 3.1 Presentation Manager. The clinical voice evaluation system provides the voice record/playback interface, patient data editing, waveform segmentation and editing, voice analysis, analysis setting, file management, procedure playback/recording, and window managements. The analysis module evaluates amplitude and pitch period contours and calculates jitter and shimmer parameters,laryngeal noise, pitch synchronous and asynchronous slices of FFT and LPC spectra, histograms and LPC spectra of perturbation sequences, etc. Keywords; pathological voice, perturbation parameters, Windows application, DSP.
