Can the text to speech voices in Captivate 8 be used in Captivate 7?

As an alternate to the  included version of the TTS Voices, I found these sources today.

THE GOOD NEWS:

The NeoSpeech.com website shows the following voices on their sales inquiry form :

Julie (Female, U. S. English)

Kate (Female, U. S. English)

Ashley (Female, US English)

Paul (Male, U. S. English)

James (Male, U. S. English)

Bridget (Female, British English)

Hugh (Male, British English)

Violeta (Female, Latin American Spanish)

Francisco (Male, Mexican Spanish)

Chloe (Female, Canadian French)

Hui (Female, Mandarin Chinese)

Liang (Male, Mandarin Chinese)

Misaki (Female, Japanese)

Show (Male, Japanese)

Yumi (Female, Korean)

Junwoo (Male, Korean)

The BAD NEWS:

Their website no longer supports the online purchase and download of these voices, it's primary focus appears to be 'TTS-in-the-cloud'

where you need licensed, downloadable, voice files.

Other options may be available via a Google Search.

As of Captivate 5.5, additional voices from Loquendo may not work. There is a restriction that only the shipped voices work. BTW, if you are planning on additional Neospeach voices, check with the vendor if they support Speech API. Only those voices which support Speech API will work with Adobe Captivate.

FYI, NeoSpeech Voices for Cp9 and other Captivate 9 download instructions are here:

What version are you looking for...Mac or Windows?

No they cannot.  You need to get the specific TTS install files for each Captivate version.

If you ask them very nicely Adobe personnel will sometimes provide links to download older versions.
