Audio File Options

  • From the menu, select Options -> Voices and File Options
  • Select the File Options panel.

The following fields are available on the File Options panel

Field Name Description
Audio File Format Select from WAV, MP3 or WMA
Bit / Sample Rate This setting is normally used to determine the quality of MP3 and WMA files generated by TextAloud.
Write to File Speed This setting applies only for SAPI4 voices, and determines how much processor is dedicated to WAV file conversion. Higher values result in faster conversion.
Silence at end of Audio File Specifies a period of silent time to include at the end of audio files. The silent time is specified in seconds, and is mainly used to prevent audio from being clipped on portable devices. A value of 0 prevents silent time from being added to your audio files.
Output File Directory The directory where audio files are written.

Choosing a Bit / Sample Rate

You will notice that different combinations of Bit Rate and Sample Rate effect the quality of your MP3 and WMA files. A general rule is to choose a Bit Rate or Sample Rate that gives you the best quality, but try to keep the Bit Rate as small as possible. Smaller Bit Rates equate to smaller audio files and faster encoding time.

When choosing a sample rate, it is important to remember that high quality digital speech can be produced at much smaller sample rates than digital music.

If you're planning to copy MP3 or WMA files to a hand-held device (like an MP3 Player), you may also need to check if your device requires a particular audio format. Some players, designed for digital music, only support sample rates in the 44kHz range, and may also require Stereo instead of Mono audio files.

Encoding in Stereo will significantly increase your audio file sizes and encoding times. Since the originating TTS output is truly Mono, it is best to use stereo encoding only if required by the portable device you're using.

The following table provides recommended settings for various voices.

Voice Engine Recommended Bit / Sample Rate
Microsoft Voices 32kpbs, 22.05kHz, Mono
Lernout & Hauspie 16kpbs, 11.02kHz, Mono
8kHz AT&T Natural Voices, 8kHz NeoSpeech 16kpbs, 16kHz, Mono
16kHz AT&T Natural Voices 24kpbs, 16kHz, Mono
Cepstral Voices, 16kHz NeoSpeech Voices 24kpbs, 16kHz, Mono
