MBROLA is a speech synthesizer based on the concatenation of diphones. It takes a list of phonemes as input, together with prosodic information (duration of phonemes and a piecewise linear description of pitch), and produces speech samples on 16 bits (linear), at the sampling frequency of the diphone database. Today Read more…
It was quite a challenge to convert eSpeak NG to an Arduino Library. In the meantime I managed to publish a first round of error corrections. The eSpeak NG is a compact open source software text-to-speech synthesizer for Linux, Windows, Android and other operating systems. It supports more than 100 Read more…
It was quite a challenge to convert eSpeak NG to an Arduino Library.

I converted eSpeak NG to an Arduino Library. The eSpeak NG is a compact open source software text-to-speech synthesizer for Linux, Windows, Android and other operating systems. It supports more than 100 languages and accents. It is based on the eSpeak engine created by Jonathan Duddington. eSpeak NG uses a Read more…
In my introductory blog, I have described that it would be cool to remove the silence from the recorded samples. If we look at one of the recordings we can see that they start and end with some silence: I have created a SilenceRemovalConverter which does exactly this. The first Read more…
I the last Blog I introduced you to my new Simple TTS Arduino Library which is available on Github. I used the Text-to-Speech (TTS) functionality of Google Translate to generate the mp3 files, which was quite tedious to do manually. Then I executed xxd to generate a .h file from Read more…
Last year I was digging into Arduino Based TTS Solutions and came to the conclusion that the available engines will not provide any quality audio and therefore recommended to consider an approach which is based on recorded audio samples. Today I took the opportunity to create the new arduino-simple-tts project Read more…
I decided to use my SAM TTS Library with the AI Thinker Audio Kit. Unfortunately I found quite some bugs in my library that I needed to correct first, but now it is working as expected. Here is the Arduino Sketch #include “sam_arduino.h” #include “AudioTools.h” #include “AudioLibs/AudioKit.h” AudioKitStream kit; SAM Read more…
As you might know from my last posts I am currently extending my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. . Originally I was of the opinion that the program logic for reading of the GPIO pins and Read more…
As you might know from my last posts I am currently extending my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. . I thought it might be helpful to have a ‘Text to Speech’ example for the Audio Kit. Read more…
