Voice Guidance
Characteristics
Feature 1. No need for studio recording
Using Epson Voice & Sound LSI for your products featuring voice guidance functions means there's no need to arrange recording studios or hire professional voice performers. This allows you to significantly reduce the product development costs and time to market. The TTS tool available from Epson makes it easy to create or modify your speech phrases.
12 languages are now available.
Japanese, English, Korean, American English, American Spanish, Canadian French, British English, German, French, Spanish, Italian and Russian.
Feature 2. Excellent sound quality for messages up to 4 times longer
| bitrate | EPSON (16kHz) |
ADPCM (16kHz) |
ADPCM (8kHz) |
|---|---|---|---|
| 1MB | approx 8min | approx 2min | approx 4min |
| 2MB | approx 16min | approx 4min | approx 8min |
| 4MB | approx 33min | approx 8min | approx 16min |
| 8MB | approx 1hour 6min | approx 16min | approx 33min |
| 16MB | approx 2hour 13min | approx 33min | approx 1hour 6min |
Epson's highly efficient encoding format allows for longer phrases with excellent sound quality. The integrated high-quality 16-bit DAC produces a "silky voice" that can be coupled with high quality sound effects.
Feature 3. Easy to integrate
Epson's voice guidance LSIs use a message protocol based on asynchronous serial interface. This means they are easily integrated into a wide range of host devices and microcontrollers, reducing development time and costs, and helping achieve faster time to market.
Feature 4. Easy Development by S1V3G340 + EPSON Speech Tool
