Speech Resources Standards
Speech processing provides powerful capabilities for improving the interaction between humans and machines, and between humans using machines. Speech processing can also be enhanced with Natural Language Processing (NLP) technology to model the human capacity to comprehend and process the content of human language, and to enable translation of a spoken sentence from one language to another, and many other intelligent linguistic applications. Speech Tools help in a great extent for providing information access interface to differently-abled persons such as people with visual and cerebral disability.
Since Speech Resources are the key building blocks for development of speech based systems, initiatives are being taken to develop speech resources for Indian Languages. To develop Speech Resources for synthesis, recognition and speaker identification, different standards and methodologies are required.
