Streams count raw bytes to the speech synthesizer from a buffer in CPU memory beginning at address address.

none

The byte stream is a previously calculated LPC (Linear Predictive Coding) formatted stream.

Note: The speech synthesizer FIFO queue is serviced when VDP accessed. Therefore, to ensure smooth access, it is advisable to perform some VDP access periodically.

Note: It is not neccessary to determine if a user's machine has a speech synthesizer fitted or not; if the speech synthesizer is not fitted then all speech related words silently exit with no error.
