Moderated Re: Vocalizer and difference in pronunciation

JM Casey

I do understand. I have a hearing loss myself and when I’m watching movies or listening to audiodramas, especially old ones, I tend to use equaliser settings to bring out more of the high frequencies in dialogue. As for the Eloquence synth, it’s top “resolution’ if you want to call it that is 11khz roughly, and the rule of thumb is that you get half that in terms of top-most frequency audible, so around 5.5khz, which is still *(supposed* to be above the frequency of most connsonants, but in practical terms, your ear can probably still discern that something is missing.

I still think Eloquence is the best synth for everyday computer use because it’s more concerned with smoothness and practical use than actual pleasurable reading. I don’t set it to speak very fast, myself, but still much faster than Vocalizer, whihch, as it’s taken from actual human voice samples, sounds like absolute garbage speaking any faster than a person can speak. However I do switch to vocaliser when I want to listen to a book “on the go” or something with my bluetooth headset. Otherwise though I just stick to refreshable braille most of the time.

Glad to understand the frequency aspect of why I might have issues hearing Eloquence clearly.  Ever so often I’ll test out voices again, but most have either too much inflection or must have some of this frequency difference.  Even in Vocalizer, I find the U.S. voices other than Nathan and Samantha seem more muffled to me.  Vocalizer.

I don't like eloquence either.  The version that used to ship with k1000 was better, but the one with jaws sounds like audio above a certain frequency is completely missing.  I use Tom Premium High on Jaws and my phone both, it seems about the best, and since I can have it on both, things are usually mis-pronounced everywhere, which bothers me less.


I used to have a Dec express, I wish I could get that voice back, maybe without the problem of not being able to shut it up quickly, that might be the best of all worlds.

It’s been a while, but, even on my iPhone, I think there is more inflection in the full or enhanced versions.  I was a Window Eyes user with Dec Talk for many years, so I don’t mind the robotic sounds of Eloquence, but there is something to the about the voices that I find hard or fuzzy to my hearing, not the diction, but the audio quality.  I like the sound clarity in Vocalizer Nathan the most, despite some of its pronunciation quirks. I like that the Compact voices are less emotive and more steady.  I’m also not one who listens to speech super-fast, so that isn’t a concern to me. I’m faster than the default for sure, but not the rocket speed I hear others use. I’m not diagnosed as hearing impaired, but have some sort of issues with my hearing of certain frequencies or tones.  I also like Microsoft Mobile Mike for clarity.

Yes, synthesizers try to guess context, if they just pronounced words, they wouldn't work near as well.  It becomes obvious when they guess wrong.  May I ask why you are using the compact version of the voice?  These are always inferior to the real versions, and most hardware won't have trouble with the full one.

I’m using Vocalizer Nathan Compact with JAWS 2021.  This is not the first case, but is striking today, so it prompted me to pose the question.  I was reading through an Excel file for work of incoming new hires.  I thought there was a typo, because the name of one of the colleges was mispronounced if I read the cell.  If I read word by word, it says the word fine.  I pasted the name into Word and the same thing occurs. Reading in any manner except word by word, causes Vocalizer to mispronounce it.  I’ve switched to Eloquence, Microsoft Mobile, and VoiceWare, all of which do not have this issue.  As I noted, this is not the first case.  Do other people notice similar issues with Vocalizer?  Is there a technical reason why a word would be pronounced differently in word by word versus line by line or say all? 


Here is the college.  The last word is the issue.  I have fixed it in my dictionary manager for now by adding a third s to the word.

College of the Holy Cross


I really love the sound  of Nathan’s compact voice, but am quite surprised by some of the strange pronunciations it has for common words.  Even the opposite of “Female” is totally off and is the first thing I adjust in a new dictionary file.
