Dialogue Constructor

If you have a complex dialogue or need to generate a dialogue via API, you can create the dialogue code using a Google Document.

1. Copy the Template:
   Follow the link to the provided document and save a copy to your Google Drive. Go to the "File" menu and select "Make a copy."

   

2. Work on the "Dialogue Constructor" Tab:

   • In Column A (Voice), input the name of the voice, select the speed, and tone.
   • In Column B (Your Text), enter the dialogue phrases.
   • Column C (Code for Speechgen) will automatically generate the Speechgen code for each dialogue line.

3. Voice Name Requirements:
   Ensure the voice name in Column A matches exactly as listed on Speechgen.

   • To find the correct voice name, check the "all_voices" tab in the document, where voices are sorted by country. Copy the desired name from there.

4. Example:

   

   • In Row 2, I entered the voice name Derek EN in Column A. Since I prefer the default speed and tone, I left those unchanged. In Column B, I added the first phrase of the dialogue.
   • In Row 3, I entered the voice name Serena EN and added her corresponding dialogue line.

   By repeating this process, I constructed the entire dialogue. In Column C, Speechgen automatically wrapped each phrase in the correct <dialog> tag.

5. Generate the Dialogue:

   • Highlight all rows in Column C and copy them using Ctrl+C.
   • Go to Speechgen and paste the content into the input field. It will look like this:

     

6. Final Steps:

   • Click Generate speech to produce the audio.
   • The entire dialogue will be generated in a single file, which you can download.
