Abstract
Method, product and system alters audio data for a synthesized voice so that when it is produced on a speaker system, it appears to emanate from a spatial position. First, the voice is synthesized into a speech waveform from a set of stored data representative of a text string using standard techniques. The speech waveform is converted into analog signals for a right and left channel. According to the invention, the analog signals to the right and left channels are altered according to position data stored with the text string so that the synthesized voice appears to originate at the apparent spatial position when the analog signals are sent to a speaker system.
