About "Partii" Project
Thai Speech Recognition Service Project
Automatic speech recognition (ASR) has become an accessible technology used extensively in modern mobile phones. Thai ASR is however in its development phase. Several components including fundamental language and speech processing tools and speech resources are required to make the technology usable for Thai speakers. Thai Speech Recognition Service is the newest project granted by NECTEC (2013-2014), aiming to provide a platform for accelerating Thai ASR research and development. The project will finally provide an open-domain Thai ASR service available as a domestic infrastructure for software developers to innovate their applications.
Partii, a Co-Creation Platform to Springboard Thai ASR
A difficulty in building practical ASR is insufficient language and speech resources. This problem could be alleviated if the speaking domain and environment are scoped. However, ASR built specifically for one task may not work effectively in the other tasks. Building open-domain ASR is hence convincing as it could be an initial tool for any task. Language model and acoustic model adaptation is then applied to enhance ASR performance if domain resources are available.
To construct open-domain ASR, large-scale language resources gathered from real usages are required. This becomes the Partii, a platform for gathering open-domain Thai speech and text. The Partii iOS App allows Thai speakers to send SMS by using their natural voice. User voices and transcribed messages will be used for continuous improvement of Thai ASR.
The Partii engine has then been improved periodically during the project term (2013-2014) and now achieve an acceptable performance for customizing to potential applications.
