Notice on sound files: The voice response features in this software work a lot better with professionally generated sound files. Upstream ships several such collections that people usually install on their own. Two prominent ones as 'Heather' for US English and 'Elin' for Swedish. Debian does not ship the sound files due to licensing and other concerns. The concerns fall into two areas: 1. Some voice generation services are proprietary. Upstream includes written texts, but the generating algorithms are often proprietary or opaque. As such, the sound files are binary blobs even though they are readily understood by any adult who speaks the language. Their inclusion in Debian main may therefore be improper. 2. Some services limit the distribution of the sound files. Most notably, the Acapela-Box service that was used to generate the Heather files states in their Terms of Service: "Limitation on Rights on Audio-Files: Except for Radio and TV Broadcast you have all rights on the audio-files purchased through the Service if they conform to this TOS. For Radio and TV Broadcast you have to get a written authorization from Acapela Group." Those terms of service appear incompatible with the GPL license upstream included in their distribution of some sound files at the time of writing. Please do not package sound files for Debian unless such concerns are addressed. Otherwise, inclusion 'non-free' may be more appropriate.
