Towards recognizing "non-lexical" words in spontaneous conversational speech
نویسندگان
چکیده
The purpose of this paper is to study and analyze both the non-lexical lled pauses and intended responses in conversational spontaneous speech, and how this can be useful in both automatic speech recognition and speaker identi cation systems. Through experiments, it was found that we are able to distinguish between words and non-lexical words in spontaneous speech using prosodic features. Consequently, a pre-recognition of such pauses using a decision-tree based CART classi er is evident. Thus, for ASR of spontaneous speech, such pauses can be either totally omitted or considered as words to be added to the dictionary of the ASR system, consequently improving the performance of such an ASR system.

Towards a unified framework for sub-lexical and supra-lexical linguistic modeling
Conversational interfaces have received much attention as a promising natural communication channel between humans and computers. A typical conversational interface consists of three major systems: speech understanding, dialog management and spoken language generation. In such a conversational interface, speech recognition as the front-end of speech understanding remains to be one of the fundam...

متن کاملA Stylometric Analysis of Conversational Speech of Aphasic Patients
In general, existing lexical tests carried out in speech therapy clinics deal with the ability to recognise written words and to name pictures of objects. Such tests assess abilities which are distinct from those required in spontaneous conversation and therefore cannot predict on their own what a patient is capable of in a communicative context. This paper aims to devise a method of statistica...

Objectives: Lexical access is the process by which the basic conceptual, syntactical and morpho-phonological information of words are activated. Most studies of lexical access have focused on picture naming. There is hardly any previous research on other parameters of lexical access such as verbal fluency and analysis of connected speech in Persian normal participants. This study investigates t...

Spontaneous, conversational speech in probable dementia of Alzheimer type (DAT) participants and healthy older controls was analysed using eight linguistic measures. These were evaluated for their usefulness in discriminating between healthy and demented individuals. The measures were; noun rate, pronoun rate, verb rate, adjective rate, Clause-like Semantic Unit rate (all per 100 words), includ...
