It is important that all sentences are separated with a space, new line, or line feed character. To make sure of this, it is recommended that a space character is routinely included after the final punctuation in a sentence. An example of what happens without this is shown below:
TextToSpeechSpeak( phTTS, "They are tired.", TTS_NORMAL );
TextToSpeechSpeak( phTTS, "I am Cold.", TTS_NORMAL );
Because there is no space, the text-to-speech system processes the following string:
"They are tired.I am Cold."
The string, tired.I, is pronounced incorrectly because the system treats it as one item instead of two words.
