Best suitable development board for the voice recognization system

Other Parts Discussed in Thread: TIDEP0066

Hello Community,

I am very new to voice recognization systems.

I would like to build an application with a circular array of MIC interfaces for voice recognization over the raspberry pi development board.

Will you please help me to know which is the suitable microcontroller or development board for me?

Regards,

Shiv Patil.

Hi Shiv,

If you are looking for a 'complete' solution, please review this TI Design and let us know your thoughts.

Hello Tom Hendrick ,

Yes, I am looking for a complete solution.

Will you please help me to more about voice recognization systems.

Hello Tom Hendrick

I would like to know further, Dose the TIDEP0066 supports multiple audio inputs. i.e. array of 4 or 8 mics.

As I am able to see in the schematic, There is only one audio input.

Hi Shiv,

The reference design supports just the one input.

Can we add an array of audio input (MIC) to it?

Shiv,

In addition to Tom's suggestion, here is another combination of systems:

Mic Array
- PCM1864-Based Circular Microphone Board (CMB) Reference Design or
- PCM1864-Based Linear Microphone Board (LMB) Reference Design
DSP Board
- 66K2G Based Audio Pre-Processing System Reference Design for Voice-Based Applications or
- C5517 Based Audio Preprocessing System Reference Design for Voice-Based Applications
Linux board
- Beagle Bone add on to the C5517 system:
  Sitara Linux ALSA DSP Microphone Array Voice Recognition
  This app note will give you an idea of replacing the BeagleBone with Raspberry Pi.

Note that a Raspberry Pi processor does not support the TDM output or multiple I2S channel created by an ADC using multiple channels. Thus, an intermediate processor (C5517 DSP) is used to take and pre-process the multiple channels.

Best regards,

Pedro

@PedroGelabert & @Tom Hendrick,

I would like to know further,

1. Dose those solutions mentioned above supporters the Amazon Alexa & Google Assistance Integrations? If yes, Is TI provide a software solution for it?

2. C5517 DSP SDK is open to users for the modifications & configurations? Ex. adding custom keywords or configuring the C5517.

3. Does TI maintains the voice processing library? How frequently updated? we are looking for the long time support for this, does TI will provide us?

4. Is there any single-chip solution with the internal DSP & audio processing?

Shiv,

1) Sorry, TI has not developed Amazon Alexa and Google Assistance Integrations

2, 3, and 4) I would defer any other DSP and processor related question to the team that supports C55x and Digital Signal Processors. Please open a thread on that group's forum.

Best regards,
Pedro
