eSpeak NG is a command line, multi-lingual software speech synthesizer for English and many other languages. We can convert text to speech using eSpeak NG in Linux and Unix-like systems. eSpeak NG is an updated version of eSpeak engine created by Jonathan Duddington.

eSpeak NG will read aloud the given text for you! It can able to speak text either from standard input or from a file. So, you can directly give the phrase to speak as input for eSpeak NG or save the text in a file and then pass that text file as an input. It uses text-to-speech to speak through the default sound device.

You can also save the output file in wav or mp3 format, instead of speaking directly. The resulting file can be played on any media players, such as VLC, SMplayer etc. It can also translate text into phoneme codes.

eSpeak NG does text to speech synthesis for 100+ languages and accents, including Afrikaans, Albanian, Aragonese, Armenian, Bulgarian, Cantonese, Catalan, Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Farsi, Finnish, French, Georgian, German, Greek, Hindi, Hungarian, Icelandic, Indonesian, Irish, Italian, Kannada, Kurdish, Latvian, Lithuanian, Lojban, Macedonian, Malaysian, Malayalam, Mandarin, Nepalese, Norwegian, Polish, Portuguese, Punjabi, Romanian, Russian, Serbian, Slovak, Spanish, Swahili, Swedish, Tamil, Telugu, Turkish, Vietnamese, Welsh and more. Some languages are supported better than others.

You can use eSpeak NG to listen to blogs and news sites and also convert text files to voice for visually impaired people. eSpeak includes different voices, and their characteristics can be altered.

eSpeak NG is a cross-platform application that supports Android, Linux, Mac OS and Windows. It is a free, open source program written in C programming language. The source code of eSpeak NG project is hosted in GitHub.

Convert text to speech using eSpeak NG

eSpeak NG is fully compatible with its predecessor eSpeak. In fact, eSpeak NG uses the same command line options as eSpeak, with several additional functionalities. Let us see a few examples.

1. Speak a phrase aloud using eSpeak NG:

$ espeak-ng "Welcome to OSTechNix blog"

Alternatively, you can use echo command to pipe the phrase as input to eSpeak NG like below:

$ echo "Excellence is not by accident. It is process, where an individual, organisation or nation continuously strive to better oneself. - APJ Abdul Kalam" | espeak-ng

eSpeak NG will read aloud the given string through the default sound device.

2. As stated earlier, eSpeak NG can read aloud the contents from a file.

$ espeak-ng -f file.txt

Or,

$ cat file.txt | espeak-ng

3. Read text input from standard input instead of a file:

$ espeak-ng

Type the word to speak and hit ENTER key. To exit, press CTRL+C.

4. If you want to save output to a WAV audio file, rather than speaking it directly, use -w flag:

$ espeak-ng  -w audio.wav "I use Arch, BTW"

5. eSpeak can able to print the phonemes of a text.

The following command will speak the word "ostechnix", and print the phonemes that were spoken.

$ espeak-ng -x ostechnix

Sample output:

'0stEkn,Iks

6. eSpeak NG supports several different voices. To list all voices supported by eSpeak NG, run:

$ espeak-ng --voices

You can also list all voices that speak a specific language, for example English (en), like below:

$ espeak-ng --voices=en

7. eSpeak NG will speak the given text using the default English voice. If you want to use a different voice, run:

$ espeak-ng -v <voice>

Example:

$ espeak-ng -vta "வாழ்க தமிழ்மொழி!"

8. For more details about eSpeak NG, refer the man pages:

$ man espeak-ng
