Estimation of voice-onset time in continuous speech using temporal measures

This paper proposes an automatic acoustic-phonetic method for estimating voice-onset time of stops. This method requires neither transcription of the utterance nor training of a classifier. It makes use of the plosion index for the automatic detection of burst onsets of stops. Having detected the burst onset, the onset of the voicing following the burst is detected using the epochal information and a temporal measure named the maximum weighted inner product. For validation, several experiments are carried out on the entire TIMIT database and two of the CMU Arctic corpora. The performance of the proposed method compares well with three state-of-the-art techniques. (C) 2014 Acoustical Society of America

Voice source characterization using pitch synchronous discrete cosine transform for speaker identification

A characterization of the voice source (VS) signal by the pitch synchronous (PS) discrete cosine transform (DCT) is proposed. With the integrated linear prediction residual (ILPR) as the VS estimate, the PS DCT of the ILPR is evaluated as a feature vector for speaker identification (SID). On TIMIT and YOHO databases, using a Gaussian mixture model (GMM)-based classifier, it performs on par with existing VS-based features. On the NIST 2003 database, fusion with a GMM-based classifier using MFCC features improves the identification accuracy by 12% in absolute terms, proving that the proposed characterization has good promise as a feature for SID studies.

Facilitated advocacy: supporting farmers to have a voice in policy making and the development of service provision

Listening to people, especially those who are poor, and involving them in policy making and decisions about service delivery processes are logical steps in building better services and improving policies aimed at poverty alleviation. This case describes a facilitated advocacy that helped to negotiate and support a role for poor people who farm and fish, to contribute recommendations for changes in services and policies that impact on their lives. The national Government of India’s Department of Animal Husbandry and Dairying and the Indian Council for Agricultural Research, both in the capital Delhi, have been linking with farmers and fishers and state government officials in the eastern states of Jharkhand, Orissa and West Bengal, in partnership with the STREAM Initiative of the intergovernmental Network of Aquaculture Centers in Asia Pacific and with the support of the UK Government Department for International Development, Natural resources Systems Program supporting farmers to have a voice(13 p.)
