Automatic Speech Recognition for Indoor HRI Scenarios

A Database for Automatic Persian Speech Emotion Recognition: Collection, Processing and Evaluation

Abstract   Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...

Automatic speech recognition for children

In this paper, the acoustic and linguistic characteristics of children speech are investigated in the context of automatic speech recognition. Acoustic variability is identi ed as a major hurdle in building high performance ASR applications for children. A simple speaker normalization algorithm combining frequency warping and spectral shaping introduced in [5] is shown to reduce acoustic variab...

Revisiting scenarios and methods for variable frame rate analysis in automatic speech recognition

In this paper we present a revision and evaluation of some of the main methods used in variable frame rate (VFR) analysis, applied to speech recognition systems. The work found in the literature in this area usually deals with restricted conditions and scenarios and we have revisited the main algorithmic alternatives and evaluated them under the same experimental framework, so that we have been...

Robust speech recognition in client-server scenarios

This paper addresses issues that are specific to the implementation of automatic speech recognition (ASR) applications and services in client-server scenarios. It is assumed in all of these scenarios that functionality in a human-machine dialog system is distributed between mobile client devices and network based multi-user media and application servers. It is argued that, while there has alrea...
