A computer-based course in spectrogram reading
نویسندگان
چکیده
We describe a computer-based course in spectrogram reading built with the CSLU Toolkit. The principal teaching tool is SpeechView, a Toolkit component that allows students to interact with speech waveform files, spectrograms, and labels. These capabilities are essential for a course in spectrogram reading. Other Toolkit modules bring additional capabilities to the course: (1) an animated face allows students to view articulators; (2) a speech synthesis system enables students to compare human and synthesized speech; and (3) a phonetic alignment package performs automatic labeling of speech. The authors have used these software components to teach three computer-based classes. We have also developed a complete laboratory curriculum, including a speech corpus designed for beginning spectrogram reading. In this article we describe the curriculum and associated speech corpus. We conclude by describing our work toward an entirely computer-based course in spectrogram reading, including: (1) enhanced spectrogram displays, (2) new labeling tools, and (3) online text, graphics, and exercises.

Classification of emotional speech using spectral pattern features
Speech Emotion Recognition (SER) is a new and challenging research area with a wide range of applications in man-machine interactions. The aim of a SER system is to recognize human emotion by analyzing the acoustics of speech sound. In this study, we propose Spectral Pattern features (SPs) and Harmonic Energy features (HEs) for emotion recognition. These features extracted from the spectrogram ...
متن کاملDesigning reading tasks to maximise vocabulary learning
Most vocabulary learning should occur incidentally through listening and reading. This is one of the reasons why a substantial extensive reading program is an important part of an English course. Extensive reading requires the learners to do large quantities of reading using material that is at the right level for them. Vocabulary learning occurs through th...

متن کاملFormalizing knowledge used in spectrogram reading: acoustic and perceptual evidence from stops
Since the invention of the sound spectrograph in 1946 by Koenig, Dunn and Lacey, spectrograms have been widely used for speech research. Over the last decade there has been revived interest in the application of spectrogram reading toward continuous speech recognition. Spectrogram reading involves interpreting the acoustic patterns in the image to determine the spoken utterance. One must select...
