1 / 49 page  RSC-4128 Speech Recognition Processor Data Sheet © 2004 Sensory Inc. P/N 80-0206-J 1 General Description The RSC-4128 represents Sensory’s next generation speech and analog I/O mixed signal processor. The RSC-4128 is designed to bring advanced speech I/O features to cost sensitive embedded and consumer products. Based on an 8-bit microcontroller, the RSC- 4128 integrates speech-optimized digital and analog processing blocks into a single chip solution capable of accurate speech recognition; high quality, low data-rate compressed speech; and advanced music. Products can use one or all features in a single application. The RSC-4128 supports Sensory Speech™ 7 technology, which includes advanced speech algorithms that add features and improve performance. Capable of running both new HMM and enhanced neural network technologies, accuracy in all kinds of noise is dramatically improved. New Speaker Verification technology is perfect for voice password security applications that must work in noisy environments. New high quality compressed speech technology reduces data rates by 5 times. New 8 voice MIDI-compatible music includes drum tracks, effectively increasing instruments beyond 8. Simultaneous music and speech rounds out the Sensory Speech™ 7 technology. The RSC-4128 also supports the revolutionary capability of creating speaker independent recognition sets by simply typing in the desired recognition vocabulary! A few keystrokes creates a recognition set in seconds without the wait or cost of recording sessions to train the recognizer, speeding time to sales. A new and unique Audio Wakeup feature listens while the RSC-4128 is in power down mode. When an audio event such as a clap or whistle occurs, Audio Wakeup will wakeup the RSC-4128 for speech or application tasks. Audio Wakeup is perfect for battery applications that require continuous listening and long battery life. In addition to improved recognition performance, the RSC-4128 provides further on-chip integration of features. A complete speech I/O application can be built with as few additional parts as a clock crystal, speaker, microphone, and few resistors and capacitors. Moreover, the RSC-4128 provides an unprecedented level of cost effective system-on-chip (SOC) integration, enabling many applications that require DSP and/or audio processing. The RSC-4128 may be used as a general-purpose mixed signal processor platform for custom algorithms, technologies and applications. Features Full Range of Sensory Speech™ 7 Capabilities Enhanced Word Spotting capability (10 SI or 4 SD words) in parallel Noise robust Speaker Independent, Dependent & Continuous Listening recognition Speaker Verification (SVWS) – Noise robust voice biometric security High quality, 3.7-7.8 kbps speech synthesis & sound effects with Sensory “SX” synthesis technology 8 voice MIDI-compatible music synthesis coincident with speech; drum track feature enables additional voices Voice record & playback Audio Wakeup from sleep Integrated Single-Chip Solution 8-bit microcontroller ROMless, 128KByte and 256KByte ROM options 16 bit ADC, 10 bit DAC and microphone pre-amplifier Independent, programmable Digital Filter engine 4.8 KBytes total RAM (256Bytes “user” application RAM) Five timers (3 GP, 1 Watchdog, 1 Multi Tasking) Twin-DMA, Vector Math accelerator, and Multiplier Built-in Analog Comparator Unit (4 inputs) External memory bus: 20-bit Address(1Mbyte), 8-bit Data On chip storage for SD, SV, templates (10 templates) Code security through no ROM dump capability Uses low cost 3.58MHz crystal (internal PLL) Low EMI design for FCC and CE requirements 24 configurable I/O lines with 10 mA (typical) outputs Fully nested interrupt structure with up to 8 sources Optional Real Time Clock Long Battery Life 2.4 – 3.6V operation 12mA (typical) operating current at 3V 2 low power modes; 1 µA typical sleep current Full Suite of Quick & Powerful Tools Quick Text-to-SI (T2SI) text entry to build noise robust SI recognition sets – low cost & push-button – no recording! Quick Synthesis for push-button speech compression Integrated Development Environment, C Compiler, Debugger & In Circuit Emulator from Phyton, Inc. |
