| Summary: | Quality of service (QoS) evaluations is significant and necessary for text to speech web
service applications. Text to speech media conversion quality measurements has general
and specific mechanisms for its functional and nonfunctional requirements. The main
objective of this thesis is to introduce QoS framework which is able to evaluate and
analyze the perceived quality of services (QoS) for text to speech (TTS) web services.
To achieve this goal, the framework combines two main mechanisms for measuring the
speech quality. General quality attributes measure the response time of TTS services,
specific quality attributes measure intelligibility and naturalness through subjective
quality measurements, which are mapped onto mean opinion score (MOS). Twenty
individuals participated the experiment to test the speech quality by comparing three
services fromtexttospeech.com, Natural Reader and Yakitome. Aggregate scores has
been used to calculate the combination of general and specific nonfunctional QoS on
TTS Web services. The result shown better scale for quality estimation, service1
(Fromtexttospeech) 47.84% is suitable TTS service provider where service2 and
service3 (NaturalReader and Yakitome) are close 31.62 and 21.53% respectively and
less preferred for listening tests to assess synthesized speech. It is essential to consider
the user’s perspective when evaluating the quality of services for media conversion
services such as text to speech (TTS) to enhance the user experience. |
