In VoiSona Talk, you can finely adjust parameters such as speech speed, volume, pitch, and style.
You can adjust parameters that affect the entire phrase (global parameters), and switch between adjustment screens using tabs to fine-tune parameters along the timeline.

Adjusting Global Parameters
For each sentence, you can adjust parameters that affect the entire sentence, such as speech speed, volume, and pitch.
- Click the "Parameter" button to open the panel.
- In the global parameter area, adjust the values by entering numbers directly or using the sliders.

Adjustable Parameters
- SPD Speed.
- VOL Volume.
- PIT Pitch.
- INTO Intonation. Lower values create a flatter tone, while higher values produce more expressive intonation.
- ALP Alpha details. Lower values make the voice sound more childlike, while higher values make it sound more mature.
- HUS Huskiness. Higher values result in a huskier voice.
Adjusting Sentence Style
You can mix multiple styles such as Happy and Angry in any ratio you prefer.
- Click the "Parameter" button to open the panel.
- In the style area, click the tab in the upper right to choose either the pie chart or bar chart view.
- Adjust the ratio of each style by entering numbers directly or manipulating the chart.

About the Ratio of Styles
When combining styles, the final output is based on the ratio of each specified value to the total.
For example, combining "Happy 100" and "Angry 100" results in a 50/50 mix.
This means "Happy 100 + Angry 100" and "Happy 50 + Angry 50" produce the same result.
The available styles and number of styles vary depending on the voice library.
Saving Parameter Settings (Presets)
You can save your adjustments to global parameters and styles as presets.
- Click the "Parameter" button to open the panel.
- Adjust the global parameters and style settings.
- Click where it says "Enter new name here" in the preset area.
- Enter the text and confirm. The preset will be saved, and you can select it from the list by clicking the "v" icon.

Selecting "Default" resets the parameter settings to their initial state.
Selecting "Reorder Presets" allows you to delete or reorder presets.
Clicking the trash icon to the right of the voice library name deletes all presets registered in that voice library.

Adjusting Advanced Parameters
Switch between adjustment screens using the tabs to fine-tune parameters along the timeline.
Adjusting Style at Specified Positions
You can specify precise positions within a sentence to apply styles and adjust the style for each position individually.
- Click the "STY" tab to display the adjustment screen.
- Click the position where you want to apply a style.

- Adjust the style as desired. The adjusted style will be applied at the specified position.
Copying Styles
Right-click the position of the style you want to copy and select "Copy."
Then, click the position where you want to apply the style, select "Paste," and the copied style will be applied there.


Adjusting Other Parameters
You can easily and freely adjust other parameters as well.
- Click one of the tabs: "VOL," "PIT," "ALP," or "HUS" to open the adjustment screen.
- Select either the "Draw Tool" or the "Line Tool."
Use the "Draw Tool" for freeform adjustments, and the "Line Tool" for linear, straight-line edits.
- Draw the lines to make adjustments.

Drawn lines are displayed in orange, allowing you to distinguish between manually edited areas and the original parameter curves.
Adjustable Parameters
- VOL Volume. Measured in dB (decibels).
- PIT Pitch. Measured in Hz (hertz).
- ALP Alpha details. Lower values result in a more childlike voice, while higher values produce a more mature tone.
- HUS Huskiness. Higher values make the voice sound huskier.
Selecting and Manipulating Ranges
In the VOL, PIT, ALP, and HUS the adjustment screen, you can use the selection tool to drag and select a range.

Holding Alt while dragging automatically adjusts the vertical range to include the current parameter.

Once selected, you can move, scale, or delete the parameters within the selected range.
Holding Shift while moving restricts movement to horizontal or vertical directions.
