SpeakUP 3 Click is a compact add-on board providing an offline speech recognition solution. This board features the VC-02, a low-cost pure offline speech recognition module developed by Ai-Thinker Technology. The VC-02 module uses an integrated voice chip US516P6 based on a 32-bit RSIC architecture core, a DSP instruction set for signal processing and speech recognition, an FPU arithmetic unit, and an FFT accelerator. The VC-02 supports offline identification of 150 local instructions, RTOS lightweight system, firmware update feature, as well as the selection of the communication method with the module.

Click library

  • Author : Stefan Filipovic
  • Date : Sep 2022.
  • Type : UART type

Software Support

We provide a library for the SpeakUp 3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for SpeakUp 3 Click driver.

Standard key functions :

  • speakup3_cfg_setup Config Object Initialization function.

    void speakup3_cfg_setup ( speakup3_cfg_t *cfg );
  • speakup3_init Initialization function.

    err_t speakup3_init ( speakup3_t *ctx, speakup3_cfg_t *cfg );

Example key functions :

  • speakup3_generic_read This function reads a desired number of data bytes by using UART serial interface.

    err_t speakup3_generic_read ( speakup3_t *ctx, char *data_out, uint16_t len );
  • speakup3_wait_for_reply This function waits up to @b wait_ms for a reply to the voice command.

    err_t speakup3_wait_for_reply ( speakup3_t *ctx, uint8_t *reply_ins, uint32_t wait_ms );

Example Description

This example demonstrates the use of the SpeakUp 3 click board by reading and displaying the voice commands reply messages.

The demo application is composed of two sections :

Application Init

Initializes driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    speakup3_cfg_t speakup3_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    speakup3_cfg_setup( &speakup3_cfg );
    SPEAKUP3_MAP_MIKROBUS( speakup3_cfg, MIKROBUS_1 );
    if ( UART_ERROR == speakup3_init( &speakup3, &speakup3_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Waits for the reply message to a voice command and displays it on the USB UART.

void application_task ( void )
{
    uint8_t reply_ins;
    if ( SPEAKUP3_OK == speakup3_wait_for_reply ( &speakup3, &reply_ins, 1000 ) )
    {
        speakup3_display_reply ( reply_ins );
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.SpeakUp3

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
