TDA7552
TTS3000 Text-To-Speech solution
The TDA7551 is part of a two-chip solution for Text-To-Speech, featuring the Lernout & Hauspie
TTS3000 engine. Two devices are needed:
A 16-bit microcontroller (ST10) for string analysis and conversion
The TDA7552 DSP for voice synthesis.
An external application sends ASCII strings to the microcontroller, which perform an analysis of the entire
sentence; language-dependent data is needed on the FLASH accessed by the ST10. As a result of the
analysis, a data stream is sent through I
2
C to the TDS7552 DSP. No external memory is required by the
DSP. The software running on the TDA7552 DSP is independent from languages.
Control through I
2
C
Management of the DSP is accomplished through an I
2
C protocol: the
TDA7552 appears as a slave i
2
c device.
Many languages available
The following languages are available:
US English, French, German, Italian, Spanish, Japanese. Other
languages available on request.
Sample rate: 11.025 kHz
