This book presents the consolidated acoustic data for all phones in
Standard Colloquial Bengali (SCB), commonly known as Bangla, a Bengali
language used by 350 million people in India, Bangladesh, and the
Bengali diaspora. The book analyzes the real speech of selected native
speakers of the Bangla dialect to ensure that a proper acoustical
database is available for the development of speech technologies. The
acoustic data presented consists of averages and their normal spread,
represented by the standard deviations of necessary acoustic parameters
including e.g. formant information for multiple native speakers of both
sexes.
The study employs two important speech technologies: (1) text to speech
synthesis (TTS) and (2) automatic speech recognition (ASR). The
procedures, particularly those related to the use of technologies, are
described in sufficient detail to enable researchers to use them to
create technical acoustic databases for any other Indian dialect. The
book offers a unique resource for scientists and industrial
practitioners who are interested in the acoustic analysis and processing
of Indian dialects to develop similar dialect databases of their own.
