If the input is a TTY, text is spoken line by line, and the output file, if specified, will only contain audio for the last line of the input.

Returns 0 if the text was spoken successfully.
Diagnostic messages to standard error are lame . Speaking failed: -1 ( return code 1 ) will occur if the input stream contains characters outside the ASCII range of , particulary x'92' apos+++ and x'96' mdash inserted by some word processors. Since say parses the entire file it will fail without saying anything if objectionable characters occur anyway in the input withuout any indication of where or how many there are.
