13 LBFE-S Client design  Speech Recognizer  Speech Synthesizer Mohammed Marouf Location Based File Exchange controlled By Speech

14 The Speech Recognizer(1 of 2)  The computer listen to the user speech, determine what is said and translate it into undersatndable format for the computer. Mohammed Marouf Location Based File Exchange controlled By Speech  Rule Grammar grammar javax.speech.demo;  Header public = Submit | Read me | Ok | Exit  Body 1. Speaker Dependent/Independent 2. Vocabulary size

15 The Speech Recognizer(2 of 2) 3. Speech Recognizer classes Mohammed Marouf Location Based File Exchange controlled By Speech Isolated words Connected words Continuous speech Spontaneous speech Voice verification/indentification 4. Quite/Noisy environment

16 The Speech Recognizer(2 of 2)  Recognition basic steps 1. Create 2. Allocate ( rule grammar & dictation grammar) 3. Load and enable grammar 4. Attach a result listener 5. Commit change 6. Request focus and resume 7. Deallocate Mohammed Marouf Location Based File Exchange controlled By Speech

17 The Speech Synthesizer  Recognition basic steps  The synthesizer is using a Concatenate voice dataset (professional speaker, paticular language and accent, recorded at paticular sampling rate) Mohammed Marouf Location Based File Exchange controlled By Speech
