You can adjust the volume of the voice in two ways:

  1. Change the volume for the entire text using Voice Settings.
  2. Change the volume for specific words or sentences using SSML tags.

Adjusting the volume of the entire text

Step 1: Enter your text in the editor and select your preferred voice.

Step 2: In the right sidebar, locate Voice Settings icon and adjust the Volume slider.

  • Increasing the value will make the voice louder.
  • Decreasing the value will make the voice softer.

Step 3: Click Convert to Speech to generate the audio.

Here in the above example I have decreased the value of Volume and the result is as follows.

Aria(Female) - English, US (volume=-14db)
0:00
/0:05

Here I have attached the default voice of the artist so that you can have a clear understanding.

Adjusting the volume for specific parts of the text

Step 1: Enter your text in the editor and select the word or sentence where you want to change the volume.

Step 2: Click on the Volume button from the top bar. In the dropdown, adjust the slider to the desired value and click Submit.

This will apply the volume SSML tag to the selected text.

For a clear understanding I have attached positive and negative volume.

Step 3: Select your preferred voice and click Convert to Speech to generate the final audio.

Here is the final result of the above scenario.

Important note

Volume adjustments through SSML are designed to maintain audio clarity. Applying very high or very low volume values can cause distortion or make parts of the speech difficult to hear, so moderate adjustments are recommended for the best listening experience.
