Measuring liveliness in presentation speech
نویسنده
چکیده
This paper proposes that speech analysis be used to quantify prosodic variables in presentation speech, and reports the results of a perception test of speaker liveliness. The test material was taken from a corpus of oral presentations made by 18 Swedish native students of Technical English. Liveliness ratings from a panel of eight judges correlated strongly with normalized standard deviation of F0 and, for female speakers, with mean length of runs, which is the number of syllables between pauses of >250 ms. An application of these findings would be in the development of a feedback mechanism for the prosody of public speaking.

Measures and perceptions of liveliness in student oral presentation speech: A proposal for an automatic feedback mechanism
This paper analyzes prosodic variables in a corpus of eighteen oral presentations made by students of Technical English, all of whom were native speakers of Swedish. The focus is on the extent to which speakers were able to use their voices in a lively manner, and the hypothesis tested is that speakers who had high pitch variation as they spoke would be perceived as livelier speakers. A metric ...

It has been claimed that in 'healthy' communication direct speech constructions contribute to the liveliness, and indirectly to the comprehensibility, of speech. AIMS To examine the effects of the occurrence of direct speech c...

متن کاملProcessing the prosody of oral presentations
Standard advice to people preparing to speak in public is to use a “lively” voice. A lively voice is described as one that varies in intonation, rhythm and loudness: qualities that can be analyzed using speech analysis software. This paper reports on a study analyzing pitch variation as a measure of speaker liveliness. A potential application of this approach for analysis would be for rehearsin...

Hidden Markov Model is a popular statisical method that is used in continious and discrete speech recognition. The probability density function of observation vectors in each state is estimated with discrete density or continious density modeling. The performance (in correct word recognition rate) of continious density is higher than discrete density HMM, but its computation complexity is very ...
