Cepstral Support FAQ

If you do not find answers to your questions please feel free to open a support ticket.

Why can I no longer buy Linux Personal voices on your online store?

Sometimes there is confusion about whether users need a Cepstral Personal voice or a Cepstral Server product. Personal voices are designed to bring TTS to one computer for users of that one computer to have their applications speak to them. Some Linux customers were using our Personal voices in phone systems and other applications without proper licensing to distribute audio to third-parties.

In order to help our customers get the licensing that is right for them, we are asking our Linux users to contact us for a quote. You can reach us either by phone 412-432-0400 or through our support ticketing system: http://www.cepstral.com/ticketing/. Our telephony server products for Linux remain available for purchase through our online store.

Free Software Trial

We encourage customers to download Cepstral voices before purchasing activation keys. This ensures that the voice works properly with your operating system and 3rd party programs. This is especially important as we have a strict no refund policy. Voices come fully functional, but you will hear a gentle reminder to activate your voice before any synthesis until you purchase the applicable activation keys from our online store.

Install Your Voice

Installing Cepstral 5 is straightforward:
  1. Download your desired voice from our Downloads area.

  2. Extract the archive, e.g. tar -xvzf Cepstral_Allison_x86-64-linux_5.1.0.tar.gz

  3. Change directory to the extracted directory, e.g. cd Cepstral_Allison_x86-64-linux_5.1.0

  4. Run the install script with elevated privileges, e.g. sudo sh install.sh

Enter Your Voice Activation Key

You can enter your activation key using the command-line swift utility. The swift executable can be found at [install path]/bin/swift. (The default path is /opt/swift/bin/swift.)

To register a voice using the swift executable, call swift with the '--reg-voice' switch. You will be prompted to enter your name, your company name, the name of the voice you wish to register, and then the activation key.

   swift --reg-voice

                 Your Name: John Q. Public

   Company (if applicable): Acme Widgets

                     Voice: David

               License Key: xx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx

You will receive feedback regarding the validity of your entries. If the information is valid, the voice will no longer contain reminders.

Additionally, you can use the '-d' or '-n' switches to directly register a particular voice based on it's install directory or voice name. In this case, you will not be prompted to enter the name of the voice to register.
   swift --reg-voice -d /opt/swift/voices/David
   swift --reg-voice -n David

                 Your Name: John Q. Public

   Company (if applicable): Acme Widgets

               License Key: xx-xxxxxx-xxxxxx-xxxxxx-xxxxxx-xxxxxx

NOTE: The voice must be registered by the user that installed the voice. If the voice was installed by root, you must register it as root.

Using Your Voice

You can use the included command line program called "Swift," which can perform several functions, such as saving the spoken output to a wav file.

Open a command shell in your operating system. Please note which directory you're in, as that is where Swift will look for text files to read (again, unless otherwise specified).

To hear Swift speak aloud, type:

swift "hello world"

To speak aloud with a specific Cepstral voice installed on your system (Emily for example), type:

swift -n Emily "hello world"

To learn more about the swift command, type swift and hit enter.
