Environment Configuration

For Windows systems, configure as follows:

Download and install the latest version of espeak-ng

Add the system environment variable PHONEMIZER_ESPEAK_LIBRARY, the value is the path to the libespeak-ng.dll file in your espeak-ng installation, for example: C:\Program Files\eSpeak NG\libespeak-ng.dll.

For Linux systems, you need to install the espeak-ng package. Execute the following command to install:

apt-get -qq -y install espeak-ng
