Abstract

Today's cell phone have a text mode or a voice mode, and there are times when one mode is definitely preferred over the other. Some examples might be (a) if a user is in a meeting and would like all the voice calls converted to text, or (b) if the user is driving and would like all text messages converted to voice. This invention of selectively converting text-to-speech or speech-to-text could be implemented in firmware or the function could be embedded into a microprocessor chip and placed in a cell phone.

Speech to Text and Text to Speech Feature for Cell Phone

Today's cell phone have a text mode or a voice mode, and there are times when one mode is definitely preferred over the other. Some examples might be (a) if a user is in a meeting and would like all the voice calls converted to text, or (b) if the user is driving and would like all text messages converted to voice. This invention of selectively converting text-to-speech or speech-to-text could be implemented in firmware, or the function could be embedded into a microprocessor chip and placed in a cell phone.

Figure 1 shows a block diagram of this invention. Microprocessor 101, cell phone interface 102, and memory 103, communicate across system bus 104. Memory 103 can be either flash, a hard disk drive, an optical disk drive, a solid state drive, etc. Microprocessor 101 controls the operation of the device via machine readable code stored within memory 103.

Figure 2 shows how the new firmware/hardware would function when placed in a cell phone and the user receives a call in step 204. In step 206, the user decides to put the phone in text mode or speech mode, this could be done via a physical switch or thru firmware using the LCD screen in Figure 4. In step 208, if the answer is no for the speech mode, meaning that the text mode was selected in prior step 206,...
