Abstract
Detecting the presence of progress tones or progress audio messages and converting these tones or audio messages to a text form that is then displayed on a wireless telephone. This capability frees the user of the wireless telephone from having to place the wireless telephone to their ear and then, lower it to actuate the keypad when contacting a service provided by a remote communication system. A digital signal processor (DSP) is utilized to detect the progress tone and to convert audio messages to text using speech to text techniques. The operations of the DSP are controlled by the user performing operations on the keypad of the wireless telephone.
