# This procedure is invoked when the user-definable block on the
# "extras" palette is selected.

# Usage: Import this code into a Python (user-definable) block and
# pass a string to be read by the voice synthesizer. If a second
# argument is passed, by expanding the Python block, it is used to specify
# the pitch level of the speaker. Valid range is 0 to 99.
