SI/SD Voice Recognizer, Recorder/Player, and Speech Synthesizer
GENERAL DESCRIPTION
The MSM6679A-110 Voice Recognition Processor (VRP) is a slave-mode device that performs
five func-tions: speaker-independent (SI) voice recognition, speaker-dependent (SD) voice
recognition, solid-state sound recording, sound playback, and speech synthesis. The highly
integrated device also provides an on-chip memory controller, Flash memory interface, analog
data conversion, Oki speech synthesizer interface, and pulse width modulation (PWM) sound
output.
For SI recognition, the MSM6679A-110 contains a vocabulary template in external memory.
Pretrained SI vocabularies eliminate the need for laborious training, as usually required by SD
products. The memory requirements are dependent on the size of the vocabulary. The MSM6679A-
110 can tolerate background noise, while providing high recognition accuracy. In its designated
operating environment, the device achieves a typical recognition accuracy of >95% (using an
Oki-defined test procedure).
For SD recognition, the MSM6679A-110 stores SD vocabulary templates, as defined by the user,
in external SRAM. The MSM6679A-110 can create SD vocabularies of up to 61 words each, with
each word using approximately 50 bytes.
In addition to providing voice recognition capabilities, the MSM6679A-110 integrates a solid-
state recorder/player, speech synthesis functions, and a tone generator. ADPCM recording/
playback provides high quality sound and efficient memory utilization. The MSM6679A-110 can
respond to spoken com-mands, verbally or with tones, via an on-chip speech synthesizer and
tone generator. For larger speech-synthesis requirements, the MSM6679A-110 also provides a
glueless MSM665x control interface for off-chip speech synthesis.
The MSM6679A-110 can interface to any application or personal computer via a serial interface
through an open, device-independent serial mode API (SMAPI). To accelerate code development,
Oki supplies an evaluation kit, and assembly and C language programs for this product.
