Speech to text in Max

Using the Google speech API

(updated locally 1/21/2024 – changed binary path to sox for homebrew /opt/homebrew/bin/sox in [p call-google-speech]

Also changed some of the UI and logic for manual writing and sending.

(updated 1/21/2021)

This project demonstrates the Google speech-API. It records speech in Max, process it using the Google API, and displays the result in a Max [message] object.

files

main patch
  • speech-to-google-text-api6.maxpat
abstractions and other files
  • JSON-google-speech.js (parses JSON response from Google API)
  • ms-counter.maxpat (manages audio recording buffer)

external Max objects

external programs

sox: sox audio conversion program must be in the computer’s executable file path, ie., /usr/bin – or you can rewrite the [sprintf] input to [aka.shell] with the actual path. In our case we installed sox using Macports. The executable path is /opt/local/bin/sox – which is built into a message object in the subpatcher [call-google-speech]

get sox from: http://sox.sourceforge.net

note: this conversion may not be necessary with recent updates to Max and the Google speech API

authorization

  • none required – so far
This may be changing.
Insert here: how to get a speech-api key from Google 

instructions

  • Open Max patch: speech-to-google-text-api6
  • Turn on audio
  • Press the spacebar. Start talking. Press the spacebar again when you are finished. The translation will begin automatically

Note: If you have a slow internet connection you may need to tweak the various delay times in  the [call google-speech] sub patch.

send Tweets using speech

Max [send] and [receive] objects pass data from this project to other projects that send Tweets from Max. Just run the patches at the same time.

Also, check out how this project is integrated into the Pandorabots chatbot API project

https://reactivemusic.net/?p=9834

Or anything else. The Google translation is amazingly accurate.

revision history

  • 4/24/2016: need to have explicit path to sox, in the call-google-speech subpatch. In my Macports version the path is /usr/local/opt/bin/sox.
  • 5/11/2014: The newest version requires Max 6.1.7 (for JSON parsing). Also have updated to Google Speech API v2.
  • update 3/26/2014 to use auto-record features developed for chatbot conversations

Arduino with touchOSC and Max

Bi-directional communication from touchOSC to Arduino using an ethernet shield.

In this version, the Macbook is directly connected to the Arduino to provide a serial monitor for status updates. 

How it works: press a toggle, or move a fader, in touchOSC – it sends a message to the Arduino which lights up, or fades, an LED – then sends back an OSC message to touchOSC to light up the toggle button. (note: local feedback should be off for the toggle button in touchOSC. This is the default)

Arduino circuit
  • Use an ethernet shield. 
  • Connect ethernet cable. (I am using a Netgear WNCE2001 ethernet to wiFi adapter)
  • LED is connected to pin 5 and ground. The shorter lead connects to ground.

download

https://github.com/tkzic/max-projects

folder: arduino-osc

files
  • Arduino sketch: OSC_ethernet_test1/
  • touchOSC screen: simple (default) uses /1/fader1 and /1/toggle1
  • Max patch: arduino-osc-ethernet1.maxpat
Arduino files and libraries

***update 1/20/2016 there is a new sketch that uses the OSCuino library from CNMAT instead of ardosc. The sketches should be interchangeable. https://github.com/CNMAT/OSC . The sketch is in a folder called: OSCuino_tz and is based on work by Trippylightning at: http://trippylighting.com/teensy-arduino-ect/touchosc-and-arduino-oscuino/

Copy the OSC_ethernet_test1/ folder to Documents/Arduino. This puts it in the Arduino sketchbook.

The sketch uses: #include <ArdOSC.h>

Download ArdOSC from: https://github.com/recotana/ArdOSC

  1. After downloading, copy the ArdOSC-master folder to /Documents/Arduino/Libraries
  2. Rename the folder to ArdOSC

This post was the key to figuring out how to make this work: http://arduino.cc/forum/index.php?topic=137549.0

Instructions
  1. Connect Arduino to Macbook via USB.
  2. Open the Arduino serial monitor to initialize the ethernet connection and display the IP address.
touchOSC
  1. In touchOSC or Max, set the target IP to the one just displayed in the Arduino serial monitor
  2. From touchOSC (or Max) send on port 8000, receive on port 9000.
  3. Use the default touchOSC layout (simple)
  4. Use /fader1 and /toggle1 to control the LED
Max
  1. Open arduino-osc-ethernet1.maxpat
  2. Set ip address in [udpsend] to the one just displayed in the Arduino serial monitor
  3. Have some fun
Fixed IP address

update 1/2016: A version of the Arduino sketch that uses a fixed IP instead of DHCP is located in the folder: OSC_ethernet_fixedIP/

The IP is set to 192.168.1.177 but you can change it to any valid address on your network.

Sending Tweets from Arduino through Pachube.com

http://www.tigoe.com/pcomp/code/arduinowiring/1135/#more-1135

from Tom Igoe

(update) I have got this working, exactly as described in the Igoe post – The code is in EthernetPachubeTweeter_tz1.

Essentially, anything that originates from the Arduino is sent to a feed in Pachube. That feed has a datastream which has a trigger which tweets any new data which arrives.

The next thing to try is figuring out whether this can be done as a single line http: request in curl, and therefore, from Max – or any other source

(update) – this is slightly broken – check out the post about converting cosm to xively https://reactivemusic.net/?p=6843]

 

RC car using Arduino with xbee radios

Bi-directional wireless control of motors

tested 5/2014

The potentiometer on the control radio changes the motor speed of the RC car. A potentiometer on the other side controls the brightness of an LED at the controller.

making things talk

The xbee code was adapted from Tom Igoe’s full-duplex Wireless example, chapter 6 – “Making Things Talk” (using an improved version from his blog: http://www.makingthingstalk.com/chapter6/30/#more-30

The xbee radios should be set up as directed – starting on p. 195

Here are the xbee settings:

ATMY ATDL ATDH ATID
Radio 1 1234 5678 0 1111
Radio 2 5678 1234 0 1111

construction

2 stacks:

1) arduino + wireless SD shield + xbee

2) arduino + motor shield + wireless SD shield + xbee  (motor shield hooked to RC car motor)

Each stack has a potentiometer, tx/rx leds, LED for remote brightness control, and batteries.

The motor shield has connections to the RC car motor and 9V battery for power.

code

Code for radio 1: xbee_full_duplex2_radio1.ino

The motor side uses a few lines of code from an instructables.com motor shield tutorial. LED brightness is linked to motor speed – sent out on pin 3 – from the Arduino sketch:

http://www.instructables.com/id/Arduino-Motor-Shield-Tutorial/?ALLSTEPS

code for radio 2 (car): xbee_full_duplex2_radio2_motor.ino

note:

When loading the sketch, set the slide switch on the Wireless-SD shield to ‘USB’ – then switch it back to “micro” to run.

If the controller radio (radio 1) is connected to a computer, open the Arduino serial monitor – or the sketch will block – and nothing will happen.

circuit layout

radio 1
  • pin A0 : input sensor (potentiometer)
  • pin 2 : tx LED
  • pin 3 : rx LED
  • pin 9: test LED (receives brightness data)
radio 2
  • pin A0 : input sensor (potentiometer)
  • pin 3: used internally for motor speed – (the motor is hooked to Channel A on the motor shield)
  • pin 4 : tx LED
  • pin 5 : rx LED
  • pin 10: test LED (receives brightness data)

Re-assign some of the pins from the xbee example so they aren’t on the same ones as the motor shield is using:  Here’s the pin layout that the motor shield uses. i.e.. these are the pins that are used in an Arduino sketch to control each motor function. This project only controls ‘speed’ on channel A (pin 3).

Function Channel A Channel B
Direction Digital 12 Digital 13
Speed (PWM) Digital 3 Digital 11
Brake Digital 9 Digital 8
Current Sensing Analog 0 Analog 1
