F0 Contour of Prosodic Word in Happy Speech of Mandarin
نویسندگان
چکیده
This paper focuses on analyzing the F0 contour of happy speech. We designed some declarative sentences and recorded them in happy and neutral expressive states. All of our speakers were asked to express these sentences in the same imaginary scene. It is known that emotion can be expressed through modifying acoustic features of speech in various ways, such as pitch, intensity, voice quality and so on. In this study, we compared the difference of F0 contour between happy and neutral speech through which we found that: (1) F0 contour plays an important role when happiness is expressed. (2) The F0 contour of happy speech displays a kind of declination pattern, but the degree of declination is less than that of neutral speech. (3) Contrasting to neutral speech, the pitch register of happy speech is higher, and the slope of F0 contour of the final syllable of each prosodic word is bigger, especially for the syllable at the end of the sentence.

Word segmentation in Persian continuous speech using F0 contour
Word segmentation in continuous speech is a complex cognitive process. Previous research on spoken word segmentation has revealed that in fixed-stress languages, listeners use acoustic cues to stress to de-segment speech into words. It has been further assumed that stress in non-final or non-initial position hinders the demarcative function of this prosodic factor. In Persian, stress is retract...

To confirm the language independency of a communicative prosody generation from input word impression vector, we synthesized communicative Mandarin speech using prosodic characteristics of communicative Japanese speech. The fundamental frequency and duration characteristics of oneword “n” utterances of Japanese were copied to Mandarin through input word attributes. From the subjective impressio...
متن کاملA study of tones and tempo in continuous Mandarin digit strings and their application in telephone quality speech recognition
Prosodic cues (namely, fundamental frequency, energy and duration) provide important information for speech. For a tonal language such as Chinese, fundamental frequency (F0) plays a critical role in characterizing tone as well, which is an essential phonemic feature. In this paper, we describe our work on duration and tone modeling for telephone-quality continuous Mandarin digits, and the appli...
متن کاملF0 Contour Analysis Based on Empirical Mode Decomposition for DNN Acoustic Modeling in Mandarin Speech Recognition
Tone information provides a strong distinction for many ambiguous characters in Mandarin Chinese. The use of tonal acoustic units and F0 related tonal features have been shown to be effective at improving the accuracy of Mandarin automatic speech recognition (ASR) systems, as F0 contains the most prominent tonal information for distinguishing words that are phonemically identical. Both long-ter...
