TaleTUC: Text-to-Speech and Other Enhancements to Existing Bus Route Information Systems
As smartphone sales increase, the demand for content for these devices also
increases. Service providers that want to reach out to as many users as possible
need to create smartphone applications that satisfy people that do not fall into
the "normal user" category. People that require non-visual feedback, such as
visually impaired persons, need output in form of auditory signals. Text-tospeech
synthesis provides this functionality, giving the smartphone the ability
to convey messages in the form of speech.
This thesis describes TaleTUC: Text-to-speech, a proof of concept text-to-speech
system for the domain of bus route information. The system uses a client-server
architecture where the server converts text to computer-generated speech signals
and provides playable audio files either directly to the smartphone, or
through a Java Servlet that provides functionality to tailor the output (e.g., audio
compression). Descriptions of other enhancements to bus route information
systems, that are are not directly related to synthesized speech, have also been
Three text-to-speech modules have been evaluated and to establish whether
there is a link between intelligibility and naturalness in synthesized speech.
Non-functional tests (transfer, response time, etc) have also been conducted
to get an impression of whether service providers that use "cloud" technology
provide a better service than an in-house system. There are no definitive answers
to these questions, but results indicate that there might be a link (however
small) between intelligibility and naturalness and that an in-house system
is still preferable in the domain of bus route information.
