A typical mobile telephone allows the user to create and send SMS (short message service) or text messages. Due to the small keypad and several letters being associated with each key, most mobile telephones adopt a predictive text system where, depending on the keys pressed by a user, the desired word is predicted. Often however, many words could be possible based on the users sequence of key presses and the user must then scroll through these options. A speech recognition unit is described where the user speaks the desired word into the microphone of the telephone, and the keypad is then used to confine the speech recognition vocabulary to words that begin with a letter corresponding to the key input. The vocabulary can be further refined by inputting the next letter of the word. |
