Ho to lower the volume of a captivate project using TTS

[Guest]

Hello Community !

I am using Text To Speech  in my adobe project. One produced, I notice that the sound is very high compared to other recordings. Is their a way to low it down for all the project ?

thanks in advance

That was due to the calibration of your microphon. Since you have more audio clips in that project, you'll have to lower the volume for each of the TTS audio clips.  If you don't want to use a dedicated Audio application (Audacity-free or Audition if you have CC) find the clips in the Library and use the right-click menu to edit them in Captivate. In the Edit Audio dialog box you have a button 'Adjust Volume'.

it is not possible pour me to do that. I am having the same problem on all my projects. I can't modify each track every time I edit the TTS. My microphone is correctly calibrated. Generally speaking the TTS is much louder than any other applications.  I always have to lower the sound on my computer every time TTS is speaking.

Why not use Audacity to have all audio clips set to the same volume? I am using Audition. Maybe someone else pops in but I don't see at this moment a global volume editing possible only for TTS. It is possible that I'm missing some feature, because I rarely will use TTS, prefer real voices.

Use some VTML code in the Text to Speech dialogue to reduce the volume as it is generated.

Note that this WILL NOT work with Microsoft voices, only NeoSpeech.

Syntax Reference:

<vtml_volume value="volume"> child elements </vtml_volume>

Attributes                Attribute Description

volume                    Set the volume within 0 to 500(%) value. Required (Anything beyond this range

                                   will be set as minimum or maximum value. +, - symbols not usable)

Example:

<vtml_volume value="50"> Now I speak at half volume. </vtml_volume>

You should see the difference in the waveform immediately after generating new audio:

Thanks a lot BDuck, this is true it worked but is their any chance something could apply to all the slides once?

Emma,

Unfortunately, not directly, as I understand it. NeoSpeech may have tools that would allow you to do this in bulk, but it won't be a simple process regardless of how you approach it.

I would:

1) Play with some of the settings, and find a speed that works.

2) Copy the opening settings to the clipboard, <vtml_volume value="50">, and then work through each slide by pasting this in front of each TTS text block.

3) Copy the closing setting to the clipboard, </vtml_volume>, and then work through each slide by pasting it at the end of each TTS text block.

4) Use the Audio -> Speech Management dialogue to 'Generate Audio' for all the slides at once.

(Just an example of the dialogue, DON'T use Microsoft Anna, it won't work.)
