1. GENERAL DESCRIPTION

The WTS701 is a high quality, fully integrated, single-chip Text-to-Speech solution that is ideal for use

in applications such as automotive appliances, GPS/navigation systems, cellular phones and other

portable products or accessories. The WTS701 product accepts ASCII (Unicode and Big5 for

Mandarin) input via a SPI port and converts it to spoken audio via an analog output or digital CODEC

output.

The WTS701 integrates a text processor, smoothing filter and multi-level memory storage array on a

single-chip. Text-to-speech conversion is achieved by processing the incoming text into a phonetic

representation that is then mapped to a corpus of naturally spoken word parts. The synthesis

algorithm attempts to use the largest possible word unit in the appropriate context to maximize natural

sounding speech quality. The speech units are stored uncompressed in a multi-level, non-volatile

analog storage array to provide the highest sound quality to density trade-off. This unique, single-chip

solution is made possible through Winbond’s patented multilevel storage technology. Voice and audio

signals are stored directly into solid-state memory in their natural, uncompressed form, providing

superior quality voice reproduction.

The chip can be programmed through the SPI port, allowing downloading of different languages and

speaker databases when made available by Winbond.
