The Audiobook Maker tab provides a user-friendly interface for creating high-quality audiobooks. This article will guide you through the process of using various drop-downs and sliders to customize and control the audio output to your liking.

Model Selection

First, navigate to the Model tab to select a trained model for your voice synthesis. For this example, we will choose a female voice model named Azuro, which was trained earlier in the Training tab.

TTS Speaker Dropdown

Next, go to the TTS Speaker dropdown. This list includes all default devices in your system as well as library options. Select the “IND speaker” from the list.

Pitch Extraction Method

The pitch extraction method used here is RMPE (Robust and efficient technique), known for its high accuracy and performance in extracting pitch from audio signals.

Slider Controls

• Index Rate: Controls the level of detail in the sample features of the voice. A scale of 0 means none of Azuro’s features are applied; a scale of 1 means a perfect clone. Set the index rate to 1 for accurate voice cloning in the output.

• Pitch Slider: Adjusts the pitch. Since both the model and TTS speaker in this example are female voices, keep the pitch slider at its default setting of 0.

• Speed: Controls the pace of the voice. Lower values result in a slower, more precise voice; set the slider to -10.

• Protect Slider: Regulates the protection level, influencing the stability and clarity of speech synthesis. Higher protection levels can help maintain clarity and prevent distortions. Adjust the slider to balance stability and naturalness.

Input Text

Input the main text in the text box. An example: selecting a Japanese model voice while the speaker is set to Hindi. Press the Convert button to see the cross-language capabilities. Once converted, you can play back the synthesized speech.

Model and Speaker Adjustment

For another example, adjust the model to a male voice like Obama and set the speaker to a female voice. Adjust the pitch slider to -12 to lower the pitch appropriately. Press convert to synthesize the speech.

Background Music Selection

Choose a background music track and use the volume slider to control the music level. A higher value on the slider means lower music volume and vice versa. Set it to around 9 for optimal mixing. Press the Combine button to attach the background music to the cloned voice.

The final output will display here, and you can enjoy a speech synthesis example of Obama reading a short story in Hindi.
