A wireless communications device includes a receiver that transmits and receives speech signals to and from a remote party via a wireless communications network. The received speech signals include information representative of one or more audible sounds associated with the remote party. The audible sounds may be, for example, words uttered by the remote party, or a predetermined audio message associated with the remote party. A speech processing unit in the user's device converts the received speech signals into corresponding text based on an operating mode of the wireless communications device. The converted text is then displayed to the user on a display. Alternatively, the remote party's wireless communication device or a network entity may convert speech to text for transmission to the user based on an indicated operating mode of the wireless communications device associated with the user.

A data processing system provides a method and apparatus for managing a shared resource between multiple processors. The data processing system includes a first processor for producing, or supplying, available sections of the shared resource, and a second processor for consuming, or allocating, the available sections within the system. The first and second processor share a memory containing a circular queue, a resource queue, for referencing available shared resource sections. The resource queue is initialized by storing a pointer to an available shared resource section in each entry of the resource queue. The second processor consumes an available section of shared resource by removing a resource pointer from a resource queue entry and sending a message signal to a mailbox message subsystem of the first processor. The first processor produces an additional section of available shared resource by servicing the resource message signal and adding a pointer to the additional shared resource section in an empty resource queue entry.
