The term Voice Shield Programmer typically refers to the software utilities, libraries, and hardware interfaces used to program Voice Shields (audio recording, playback, or speech recognition expansion boards) for microcontrollers like the Arduino Uno.
Because “Voice Shield” can refer to a few different hardware modules, the programming software or environment varies based on the specific chip or shield being used. 1. ISD Programmer (Audio Recording & Playback Shields)
For voice shields based on the ISD1700 series microchips (such as the popular ISD1790PY voice shield), the programming software is called the ISD Programmer.
Purpose: This software allows you to manage voice messages, sound effects, and multi-track audio recordings directly from a computer.
Key Features: It helps calculate precise memory locations and timestamps for each recorded audio track.
How it works: Audio files (like .wav or .mp3) are transferred via the programmer software into the voice shield’s onboard non-volatile memory. The shield can then be controlled dynamically via a SPI interface using an Arduino. 2. EasyVR Commander (Speech Recognition Shields)
If you are dealing with a voice recognition shield rather than a simple playback shield, you are likely using the EasyVR Shield. Its corresponding programming tool is the EasyVR Commander.
Purpose: It is a graphical PC application used to generate, train, and test custom voice commands.
Key Features: It allows you to define “Speaker Independent” (pre-set) or “Speaker Dependent” (trained by your specific voice) command groups.
Code Generation: Once your voice commands are programmed into the tool, it automatically generates the necessary code to paste directly into your programming environment. 3. Arduino IDE Libraries (Integrated Dialog Shields)
Some modern voice shields bypass standalone desktop programmers entirely by embedding the logic directly into firmware. A prime example is the MOVI Voice Dialog Shield. Voice Shield for Arduino – Audio
