AI extensions for the eCraft2Learn project

A guide that describes the extensions, projects, and the larger context currently consists of five chapters:

Sample programs

The following demonstration programs use the AI Snap! blocks. They run best in the Chrome browser.

**Listen to generated speech with random pitch, rate, voice, and language**
(requires speaker/headphones)

**Speak single word commands to a sprite (with synonym support)**
(requires microphone and speaker/headphones)

**Speak full sentence commands to a sprite (with keyword search)**
(requires microphone and speaker/headphones)

**Create funny sentences by verbally answering questions**
(requires microphone and speaker/headphones)

**Customise stories by verbally answering questions**
(requires microphone and speaker/headphones)

**Ask questions of Wikipedia**
(requires microphone and speaker/headphones)

**Ask about the weather anywhere in the world**
(requires microphone and speaker/headphones)

**Listen to a description of what is in front of the camera**
(speaker/headphones, webcam, and API key(s))

**Listen to a description of what is in front of the camera in response to you speaking**
(requires microphone, speaker/headphones, webcam, and API key(s))

**Train the turtle to move depending on which way your finger is pointed**
(requires webcam and a GPU)

**Train the the turtle to move depending on the voice commands you give**
(requires microphone)

**Train the turtle to move left or right depending on which way you lean**
(requires webcam and a GPU)

**Play *Rock Paper Scissors* using machine learning**
(requires webcam, speaker/headphones and a GPU)

**Play *Simon Says* using machine learning**
(requires webcam, speaker/headphones and a GPU)

**Play *Guess My Word* that works by turning words into 300 numbers**
(requires speaker/headphones and optional microphone)

**Turn a photo into 8 different paintings**
(requires webcam (but easily modified to use any image instead) and a GPU)

**Translation using 300 numbers and a word list with 2.5% coverage**
(no special requirements)

GPU required for chapter 4 image recognition and some demos

Nearly all modern computers have a GPU. Without one or with a very primitive one programs using machine learning may run very slow. For example, the image machine learning commands run very slowly on Raspberry Pis. The audio training primitives, however, do run well on Raspberry Pis.

Using the AI blocks in your projects

You can import this file into your existing or new projects. The AI blocks can then be found in the Snap! palette under

, or

Adding speaking to your programs	Speech synthesis requires only speakers or earphones
Adding listening to your programs	Speech recognition requires a microphone (builtin or connected to a USB port)
Adding image recognition to your programs	Requires a camera (builtin or connected to a USB port) and registering to get API keys
Adding machine learning to your programs	Many examples rely upon a camera. It is very slow unless your device has a GPU.
Working with words and language New!	No special hardware requirements
