Text to speech conversion method

A user while traveling may call an operator in an information/call center to request directions to a desired destination. In response, the operator obtains a directions file containing the requested directions. To facilitate the user receiving directions in installments in accordance with the invention, the directions file has an indicator associated therewith. The requested directions are read from the directions file to the user by an interactive voice response (IVR) unit via synthesized voice. The indicator is used to indicate in the file which direction is to be read to the user. The user may terminate the call after hearing a desired quantity of directions. When the user subsequently needs another installment of directions, the user may call back the IVR unit which then continues to read directions in the directions file from where the associated indicator indicates. The above process can be repeated, thereby enabling the user to controllably receive the directions in installments.
