7. FUNCTIONAL DESCRIPTION
As a real System-On-Chip solution, the WTS701 performs the overall control functions for host
controller and text-to-speech processing.
The WTS701 system architecture consists of the following functions:
• Serial interface to monitor the SPI port and interpret commands and data
• Text normalization module to pre-process incoming text into pronounceable words
• Words to phoneme translator, which converts incoming text to phoneme codes
• Phoneme mapping module that maps incoming phonemes to words, sub-words, syllables or
phonemes present in the MLS memory
• Volume and speed adjustments
• Digital and analog output blocks for off-chip usage
The WTS701 system performs text-to-speech synthesis based on concatenative samples. The units
for concatenation can vary from whole words down to phoneme units. The convention is that the
larger the sub-word unit used for synthesis the higher the quality of the speech output. A corpus of
pre-recorded words is stored in Winbond’s patented multilevel storage (MLS) memory and a mapping
of the various sub-word parts is held in a lookup table. The speech creation is achieved by
concatenation of these speech elements to produce words. The system process flow is shown in
Figure 5.
