Speech commands are all the rage on everything from digital assistants to cars. Adding it to your own projects is a lot of work, right? Maybe not. [Electronoobs] shows a speech board that lets you easily integrate 255 voice commands via serial communications with a host computer. You can see the review in the video below.

He had actually used a similar board before, but that version was a few years ago, and the new module has, of course, many new features. As of version 3.1, the board can handle 255 commands in a more flexible way than the older versions.

Although the board can handle 255 commands, it only listens for 7 of those at one time, which is an odd limitation. However, the older board had even stricter limits where you could only listen to one of three groups and each group had 5 commands. With the new board, you can pick any 7 of the 255 commands to be active at once. You can then replace some of the 7 with other commands based on context. For example, you might listen for a main menu command and, based on that selection, listen for a different set of second-level commands.s

The interface is either serial or I2C. We couldn’t help but think that if you could listen to 12 or 15 commands at once, you could have a set for listening to numbers which might be handy. Maybe version 4?

You train the commands using a microphone with an interactive wizard-like setup. The eventual target for this is a robot, but for now [Electronoobs] is just lighting up LEDs on command. But it looks very easy to use for whatever purpose as long as you can work out the limit of 7 commands.

It is harder to do, but you can make an Arduino process speech by itself. Even easier, with a bigger processor.

Programming is a valuable skill, though one that can be daunting to learn. Throw hardware in the mix, and things ratchet up another level again. However, there are many projects that have sought to reduce the level of difficulty for newcomers. HeyTeddy is a new project that allows users to program an Arduino with voice commands, and the help of on-screen tutorials.

It’s a system that initially sounds cumbersome, but through smart design, is actually quite streamlined. Users can talk to the system, which uses an Amazon Alexa device for natural language voice recognition. This enables HeyTeddy to respond to questions like “how do I use a flex sensor?” as well as direct commands, such as “Set pin 10 to 250”.

The demo video does a great job of demonstrating the system. While the system is not suited to professional development tasks, its has value as an educational tool for beginners. The system is able to guide users through both hardware setup on a breadboard, as well as guide them through tests when things don’t work. Once their experience level builds, code can be exported to the Arduino IDE for direct editing.

It’s a great tool that has plenty of promise to bring many more users into the hardware hacking fold. It’s out of the workshop of [MAKInteract], whose work we’ve seen before. Video after the break.

MOVI, a standalone speech recognizer shield for Arduino

arduino, shield, speech recognition, voice Commenti disabilitati su MOVI, a standalone speech recognizer shield for Arduino 

20150701024028_MOVI

MOVI is an offline speech recognizer and voice synthesizer that adds voice control functionality to any Arduino project

MOVI stands for My Own Voice Interface! It is the first standalone speech recognizer and voice synthesizer for Arduino with full English sentence capability:
Up to 200 customizable English sentences.
Speaker independent
Standalone, cloudless and private
Very easy to program

MOVI provides an alternative to buttons, remote controls, or cell phones by letting you use full-sentence voice commands for tasks such as turning devices on and off, entering alarm codes, and carrying on programmed conversations with projects.

MOVI is plug and play! Connect the shield to your Arduino Uno or compatible board, connect an optional speaker, and you’re ready to go.

Monster_post2

It’s time to introduce you to another great tutorial made for  Intel Edison.  Mimic Monster is a project allowing you to record soundbites and playing them back manipulated.
In this step-by-step project, everyone who is interested in audio features and mods , can find useful information on how to manipulate audio files and create amazing effects from your voice.

Grawr! It’s a mimic monster! What did you say? Grawr! It’s the mimic monster!

Having landed on Earth, this little alien needs you to teach it how to speak. Speak into its audio antenna and it will repeat your words back. Press a button and change its pitch. In this tutorial, you will learn in more detail, how to work with a USB sound card, a microphone, and a speaker.


Before you begin, make sure you’ve followed through Intel® Edison Getting Started guide, and our previous tutorial, the Intel® Edison mini-breakout Getting Started Guide.

Control your Arduino with voice commands using an Android smartphone! Before we make a voice activated home automation system, we must first learn the basic principles of the experiment. This guide will let you command the Arduino using your Android smartphone and a HC-05 Bluetooth module.

The designer of the app did not include a sample code. I looked for alternatives in Google’s PlayStore but none was as good as the app that I’ve found. Luckily, I was able to figure it out although it took me a while to program it. Sorry IOS users, this app isn’t available in Apple’s app store :/

Talkbot: an Arduino-driven robot for beginners

talkbotguts

It isn’t exactly WALL-E, but [Bithead's] affordable introduction to robots – Talkbot – is made out of a trash can. This little guy runs off an Arduino and comes packed with features, including a voice chip, a motor shield, and a pair of bump sensors. Talkbot will cruise around until a bump sensor slams into an obstacle. One of his prerecorded messages will then play through the speaker while he backs up, turns, and tries to find a clearer path.

According to [Bithead's] build log, tracking down the right bargain voice chip was a bit of a hassle; he skipped over the text-to-speech options only to be stalled by vendor issues. He finally settled on a clone of Sparkfun’s WTV020SD chip sourced from eBay, which allows you to access pre-recorded WAV files stored on a Micro-SD card. The robot’s body comes straight off the hardware store shelf, with PVC pipe for arms and a polystyrene base to hold all the parts.  At the bargain price of $110, [Bithead's] students will have a true hacker experience cobbling the Talkbot together rather than using a prefab kit.

Be sure to see Talkbot  in a video below, performing either his green-eyed “friendly mode” or red-eyed “grumpy mode,” which dictates how pleasantly he responds to obstacles. Need something more advanced? Check out the tentacle robot, just in time for Halloween.

A Voice Shield for Arduino – Give Voice to your Ideas!

Audio-Shield5

This Voice shield can be useful to integrate voice messages in alarm systems, to implement generic I/O controls in home automation or even in home security applications: something like playing an alert when a person or a vehicle approaches any given protected area. The use cases are many and limited only by your imagination!

While this shield can operate stand-alone, it can be better managed through and SPI interface: by connecting this with Arduino it can take control of the speech synthesis.
