Adjusting Parameters

日本語 / English
In VoiSona Talk, you can finely adjust the speed, volume, pitch, style, and other aspects of the synthesized speech. You can adjust the parameters that affect the whole sentence (global parameters), and switch the tabs of the adjustment pane to adjust more detailed time-series parameters.

Adjusting the Parameters of the Whole Sentence

For each sentence, you can adjust the parameters that affect the whole sentence, such as speed, volume, and pitch.
  1. Click the "Parameter" button to open the panel.
  1. In the global parameter area, adjust the values by entering them directly or by using the sliders.
ℹ️
Adjustable parameters
  • SPD Speed.
  • VOL Volume.
  • PIT Pitch.
  • INTO Intonation. Lower values sound flatter, and higher values give stronger intonation.
  • ALP Alpha details. Lower values sound more childlike, and higher values sound more adult.
  • HUS Huskiness. Higher values sound huskier.
ℹ️
Double-click a slider to return it to the default value.

Adjusting the Style of a Sentence

You can mix multiple styles such as "Happy" and "Angry" in any ratio you like.
  1. Click the "Parameter" button to open the panel.
  1. In the style area, click the tab at the upper right to select the pie chart or the bar chart.
  1. Adjust the ratio of each style by entering the values directly or by operating the chart.
ℹ️
About style ratios
When styles are combined, they are synthesized according to the ratio of each value to the total. For example, combining "Happy 100" and "Angry 100" gives 50% each. That is, "Happy 100 + Angry 100" and "Happy 50 + Angry 50" mean the same thing.
ℹ️
The available styles and their number depend on the voice library.

Saving Parameter Settings (Presets)

Adjustments to the global parameters and styles can be saved as presets.
  1. Click the "Parameter" button to open the panel.
  1. Adjust the global parameters and styles.
  1. In the preset area, click where "Enter new name here" is displayed.
  1. Enter the text and confirm. The preset is saved, and you can select it from the drop-down menu by clicking "v".
ℹ️
Select "Default" to return the parameter settings to their initial state.
ℹ️
Select "Reorder Presets" to open the "Preset Parameters" dialog, where you can delete or reorder presets. Clicking the trash can button to the right of a voice library name deletes all presets registered for that voice library.

Adjusting Other Parameters

The other parameters can also be adjusted easily and freely.

      2. ℹ️
      Drawn lines are shown in orange so that you can tell the drawn part from the generated parameter line. While you drag, the time and the value at the pointer are shown in the status bar at the bottom of the window.
ℹ️
Tools of the adjustment pane
  • Selection Tool Selects a range of the parameter (see below).
  • Draw Tool, Line Tool Draw the parameter freehand or in straight lines.
  • Eraser Tool Drag over a drawn part to return it to the generated line.
