Run the espeak command using docker container

To provide a speaker device to a Docker container for running espeak-ng, you can use the — device flag when running the container. This flag allows you to pass a host device into the container.

Here’s an example command to run a Docker container with access to the speaker device:

docker run -it --name my-container --device /dev/snd:/dev/snd ubuntu:latest

In this command:

• -d starts the container in detached mode.
• — name my-container sets the name of the container to “my-container”. You can replace “my-container” with the desired name.
• — device /dev/snd:/dev/snd maps the host’s sound device (/dev/snd) to the same location inside the container (/dev/snd).
• your-image:tag specifies the name and tag of the Docker image you want to run. Replace “your-image” with the actual image name, and “tag” with the desired version or tag.

By including the — device /dev/snd:/dev/snd flag, the Docker container will have access to the speaker device on the host system. This allows espeak-ng or any other sound-related application running inside the container to utilize the speaker device.

Please note that you may need to adjust the device path (/dev/snd) if your system uses a different sound device location. Additionally, ensure that the host system has the necessary permissions and audio drivers properly configured to access the speaker device.

You will enter inside docker container, run following command to install espeak-ng inside docker.

apt update
apt install espeak-ng

Use following command to speak using “espeak-ng”:

espeak-ng "Hello world"

Thank you.
