PS. Having tested just about all Android TTS engines/voices (both free and not so much), I have settled on Nuance Vocalizer Premium for a balance of voice quality and resource usage. I just think it sounds the best, but that's just my opinion, of course. If you want it, you may have to search a bit...I don't remember where exactly I got the engine or voices, but it was not from Google Play.
Where can I get Nuance Vocalizer Premium? I know Nuance sounds better on WinCE, but Loquendo sounds pretty good on Android. I would like to try Nuance on Android to see if it's better. Thanks!
I could not find it without stepping on other Forums' toes, so I uploaded what I have myself. It's a big download (900MB +) and requires the same on an SD Card.
Nuance Vocalizer Premium (w/two voices Tom and Ava US English):
Install.part1.rar 195MB [Only registered and activated users can see links. ]
Install.part2.rar 195MB [Only registered and activated users can see links. ]
Install.part3.rar 195MB [Only registered and activated users can see links. ]
Install.part4.rar 195MB [Only registered and activated users can see links. ]
Install.part5.rar 44MB [Only registered and activated users can see links. ]
Basic Instructions (not for beginners, probably)
Spoiler: See How
Additional Voices/Languages: [Only registered and activated users can see links. ]
(rename downloaded file from *.nvda-addon to *.zip, extract, and copy to SD Folder structure as shown in my download)
Each language in it's own subfolder under VocalizerEx...enu = English US, etc
Note: "Compact" voices will not work with the "Premium" engine..only (probably) Plus and Premium High. I have not tested "Plus".
Download all RAR parts and extract on PC. Copy entire VocalizerEx folder in download to the root of SD Card. Add any other voices/languages downloaded separately. Install APK, go to Android Settings>Language and Input>Text to speech output> Enable VocalizerEx TTS, adjust voice settings as desired, etc.
All of this tested under KitKat on a medium range Android Phone. How it may perform under other circumstances is unknown.
Thanks Mike Hunt. Your voice file works for iGO Primo 2.4 22.214.171.1247625 on my mobile phone, running Android 4.01 with Nuance Pro TTS for android.
Shall try iGO Primo 2.4 9.6.29.xxxxx later on to see if it works as well.
Edit: Thanks Mike Hunt. Your voice file works on iGO Primo 2.4 126.96.36.199xxxxx latest version. Magic!!
If all of the above checks out, on your PC, open the voice.zip with WinRar or similar, then open info.ini with notepad and remove these two lines: tts_langname="eng"
(some Android Igo versions require them, some do not)
Then save info.ini, update the zip archive, copy the new file to your Igo/content/voice file on your device (delete previous version if it's still there), and try again.
Man, you saved whatever is left of my hair...it was unnerving to see TTS sometimes working and sometimes not, with the SAME engine and voice file. I removed the tts_engine setting and now it works with all 3 engines I have installed on my Note3.
Thanks for the tip!
