Underlying quality dimensions of modern telephone connections
It is the aim of the present paper to analyze the perceptual quality dimensions of modern telephone connections. Such connections differ from standard connections in their timevariant characteristics (e.g., due to Voice-over-IP transmission or due to noise reduction algorithms) and their user interfaces (e.g., hands-free terminals). With the help of two independent auditory experiments with sub...
متن کاملMandarin telephone speech recognition for automatic telephone number directory service
This paper discusses an HMM-based Mandarin telephone speech recognition method for implementing a prototype system of automatic telephone number directory service. It adopted the GPD/MCE training algorithm to train the HMM models for 100 final-dependent syllable initials and 40 syllable finals. The SBR method was used to compensate the speaker and channel effects. Besides, an RNN-based pre-clas...
متن کاملAutomatic Language Identification of Telephone Speech
II Lincoln Laboratory has investigated the development of a system that can automatically identify the language of a speech utterance. To perform the task of automatic language identification, we have experimented with four approaches: Gaussian mixture model classification; single-language phone recognition followed by language modeling (PRLM); parallel PRLM, which uses multiple single-language...
متن کاملAutomatic Evaluation of Tracheoesophageal Telephone Speech
The tracheoesophageal (TE) substitute voice is currently state–of–the–art treatment to restore the ability to speak after laryngectomy. The intelligibility while talking over a telephone is an important clinical factor, as it is a crucial part of the patients’ social life. An objective way to rate the intelligibility of substitute voices when talking over a telephone is desirable to improve the...
متن کاملA Voice-controlled Automatic Telephone Switchboard and Directory Information System
In this paper, we present the Philips automatic telephone switchboard and directory information system PADIS. PADIS understands natural-language requests in fluently spoken German. The system offers telephone, fax, and room numbers, email addresses, private phone numbers, and direct call completion. A setup with a 500-entry database is currently in a field test in our research laboratory and ha...
