TTS

Text-to-Speech Library for Arduino

• checkout this project into your sketchbook/libraries folder
• requires an amplifier on the PWM output pin (see below)
• see blog articles

Supported Hardware

• ATmega328-based Arduinos (e.g., Uno, Pro, Pro Mini, etc.): pins 3, 9, 10
• ArduTouch: pin 9
• ATmega1280-based Arduinos (e.g., Mega): pins 44, 45, 46
• Arduino Leonardo: pin 5
• Arduino Due: pins DAC0 or DAC1
• Teensy 3.2: pin A14
• Teensy 3.5, 3.6: pins A21, A22
• Teensy LC: pin A12
• ESP8266: pins 0 to 16 (with analogWrite())
• ESP32: DAC1 or DAC2 (pins 25 or 26)

Amplifier

Component choices in this circuit aren't very critical:

• 22k (vs 27k) and 47n (vs 10n) parts in the input low-pass filter
• 100n (vs 10u) bypass capacitor between pin 7 and gnd
• Used the inverting input instead of the non-inverting one (although in this circuit I noticed no difference)
• 47n (vs 100n) output snubber capacitor

Credits

• original implementation by Clive Webster in Webbotlib
• ported to Arduino by Gabriel Petrut
• Stephen Crane modified it to use pins other than pin 10 with the help of this tutorial
• manitou48 added support for Leonardo and ARM processors with DAC (Teensy, Due)

tts's Issues

how to create english.h ?

i want to create my own languange, can u explain how to create similiar like english.h ?

Schematic Diagram

The link to the schematic on the readme doesn't seem to point to a page with the schematic.
Here is a link that is still active:
http://www.tehnorama.ro/wp-content/uploads/2010/06/Arduino-LM386.png

Even better might be to create a sub directory and add it to the repository
so it is never lost.

english.h

Arduino IDE 1.0.5 gave an error saying that an "attribute" for SoundData need to be a const in the english.h file, once I found the SoundData I added "const" after "static" and all seems to working.
This is great work, and glad to have found this on github, after trying without much luck to get the old TTS library working that Clive Webster wrote, this was a joy, even if I did have to modify one of the files. Thanks

Does this Library support the new ShieldBuddy TC275

Title.

Support other languages

add new language

How do I add a Turkish language?

how to get a pure sound or hearable voice

hello sir,
i am making the ths TTS using ardunio , I made the all connection as per the ckt diagram and conneection defined in the code.the problem that facing to me is that can't get the pure sound or hearable voice. the speed of the output voice is very fast i want it slow.for example This is the generated voice sample. It is trying to say “Hello Master, how are you doing? I am fine, thank you.”:
sample_output.zip
plz help me sir for getting normal voice .waiting for your reply plz help me.

Support non-avr processors

DAC on ESP32 (use dacWrite)
PWM on ESP8266

Does not work withesp8266, tried it with the node mcu and the wemos d1 mini. Produces no sound on the output

Additional Output Methods

I have added some additional output via a callback method and to a Stream.
Would you be interested in a pull request ?

How to setup this code in Arduino

Hi sir,
Please tell that how to setup this code in Arduino.
As there are many files in it

Support Circuit Playground Express

master...manitou48:master

EXPLANATION REQUIRED

Respected Sir

  I am trying to learn learn how to create text to speech library as part of my course curriculum.can you please explain the code you have provided as it is immensely difficult to understand it without any help.I shall be highly obliged to you.

Thank you
