摘要： Speech sound recognition is made using a reduced number of speech parameter elements, e.g., five correlation coefficients rather than sixteen spectral coefficients. The five correlation coefficients are derived from comparison of the spectral coefficients of unknown or standard sounds against the spectral coefficients of five highly-separable vowel-like sounds. Then, unknown-sound correlation coefficients are compared with standard-sound coefficients for recognition.

摘要： PROBLEM TO BE SOLVED: To enable anyone to use a voice recognition system effectively by performing a voice recognition while using the acoustic model of the voice recognition system suited for the feature of a speaker estimated in accordance with a detected physical feature information of the speaker to compensating the degradation of a recognition rate to be caused by depending on feature of the voice of a user. SOLUTION: The feature of the user is extracted from a voice 100 in the personal information extracting part 310 of the voice of the user by using the voice 100 or measured results of a mat type scale 160 and/or a sheet position detecting meter 170 as input information. Moreover, when the measured information of the mat type scale 160 and/or the sheet potion detecting meter are used as the input information, the information are converted into information of a weight or a stature in a physical feature converting part 320 and these are converted into the feature of the voice of the user in a voice feature conversion part 330. Then, a speaker adaptation is executed in a speaker adaptation part 350 for acoustic model so that an acoustic model to be used in the voice recognition becomes the acoustic model suited for the user based on the personal information detected in this manner.

摘要： PROBLEM TO BE SOLVED: To obtain a speech translation terminal which does not lose an advantage that voice has and is easy to use by controlling a voice recognizing means, a speech synthesizing means and a language converting means from an external device when it is confirmed that the terminal is connected to the external device. SOLUTION: Voice that is inputted from a microphone 11 is sampled and inputted by an AD converting part 12. A voice recognizing part in a program in a single operation mode performs characteristic extraction of the inputted voice according to a CPU 1, calculates similarity by using standard patterns of all of sentences and words which you want to make recognized and outputs a sentence (word) of a standard pattern that has the highest similarity as a solution. Also, a translating part retrieves parallel translation of recognition results and an operation type, and when the operation type is a 'sentence', it transfers the recognition results and a parallel translation sentence to a liquid crystal display controlling part 8 and shows them on a liquid crystal display 7. A voice synthesizing part synthesizes synthetic voice from the sent parallel translation sentence, a DA converting part 13 converts it into an analog signal and outputs it from a speaker 14. In this way, if you inputs, e.g. 'OHAYO (Good Morning)' by voice, it answers with 'Good Morning'.
