This is third post in a series on Text-to-Speech for eLearning written by Dr. Joel Harband and edited by me (which turns out to be a great way to learn). In the first two posts, Text-to-Speech Overview and NLP Quality and Digital Signal Processor and Text-to-Speech, we introduced the text to speech voice and discussed issues of quality related to its components: the natural language processor (NLP) and the digital signal processor (DSP). In this post we will begin to address the practical side of the subject: How can e-learning developers use Text-to-Speech (TTS) voices to narrate their courses? What tools are immediately available?
There are a number of possibilities available today for using TTS for eLearning; they fall into two categories or approaches:
In this article, we are going to concentrate only on using TTS Stand-Alone tools to create audio files that are embedded into a course.
TTS stand-alone products can be used by eLearning developers irrespective of the authoring tool they are used. Several of the voice vendors offer on-demand TTS voice web services which accept text and produce sound files. Here are a few of the top web services for TTS:
| Company | Web Service |
| Loquendo | |
| NeoSpeech | |
| Acapela-Group |
These web services have the advantages:
Disadvantages
This can be a major disadvantage and cause significant extra steps. Because of this, we are going to concentrate on a particular desktop stand-alone product to illustrate the eLearning production workflow.
Acapela-Group offers a desktop stand-alone product, Acapela Virtual Speaker, that is better suited to eLearning production than most of the web services solutions listed above.
As an example, let’s see how to work with Acapela Virtual Speaker. Virtual Speaker works with input text files (the narration scripts) and output sound files organized into directories. Narration scripts (text files) are stored for easy updates and the system makes it easy to generate the associated sound files based on updates. The sound files are generally easy to find and access from any authoring tool.
To create a sound file from narration text for an authoring tool using Virtual Speaker, you perform the following:
To import the sounds files into the authoring tool use the File Import function of the tool to import the file from the working folder as required.
It sounds really easy and it is. Stand-alone TTS tools are used to create sound files just as you would if you had a human recording audio for the course. These sound files then need to be associated with the content using the authoring tool. In later posts, we’ll get into more specific comparisons of TTS vs. human narration. In terms of taking the resulting audio files and using them via an authoring tool, the level of effort is similar.
Of course, both human narration and TTS tools that produce audio files means that it takes some work to get the audio files embedded in the authored course, including importing the files and in some cases synchronizing them with a time-line editor. Tools that have embedded TTS, like Adobe Captivate, make this significantly easier. And if you make changes to the script, you will need to create new audio files and import them again. This is much easier than having to go through another round of narration. But it still takes work.
Some readers may be wondering why we haven’t mentioned the TTS “personal reader” products such as: Natural Reader , TextAloud, Read the Words, and Spoken Text as possibilities for eLearning tools. The reason is that sound files produced by personal readers are for personal use only and are not allowed, by license, to be distributed. This restriction means that these products cannot be used for eLearning, where sound files are distributed to learners. We’ll talk more about this important subject in a future post.
A colleague just asked me if I knew anyone who was using Augmented Reality for learning. I’m not and I gave him the standard advice about looking through LinkedIn Guide for Knowledge Workers, LinkedIn for Finding Expertise, and Searching for Expertise - LinkedIn Answers. He did that, but didn’t find particular people. Probably I need to update my posts because there have to be lots of people who would be involved in training and augmented reality found via LinkedIn. I just tried a search for “augmented reality” as a keyword along with either title contains “training” or “learning” and found some interesting folks.
My next suggestion was to use eLearning Learning to search. This gave rise to the additional of a new keyword Augmented Reality on eLearning Learning. You may have wondered where the keywords come from. :)
Actually, this leads to quite a treasure trove of great posts:
And this naturally leads to both the people/companies in the various case studies as well as suggests some folks to contact such as Judy Brown, Karl Kapp, Lars Hyland, David Hopkins and more. At least they’ll likely have a bit more clue as to who to talk to.
If you have suggestions for my colleague, we are all ears.
I received a question this week related to Discussion Forums for Knowledge Sharing at Capital City Bank:
I successfully launched a discussion forum for a small group of lending assistants within my bank. That forum is still up and running. Since that time, I have attempted to introduce the discussion forum tool to two other work groups within the bank but I have not been very successful. I’ve used examples from the lending assistants as well as other benefits of the tool to demonstrate how its use would benefit the bank and these work groups. They see the benefit of the tool in a strict learning environment, but have difficulty seeing its use in an expanded role.
One of the things that this group has identified as one of their “problems” is that they receive too many emails. I presented the discussion forum as a solution to this problem, in that it would reduce the number of emails they receive because the information would not be in their in-box, and more importantly would allow discussion between the all the members (one to many) rather than one to one or one to a few. They pushed back because they felt that this was just one more place to go and one more thing to do. They were also concerned about the accuracy of the information that was published on the forum. I pointed out the benefit of correction of inaccurate information on a discussion forum is that it is visible and correctable - unlike information that is sent through email or other back channels of communication. I could go on… but I’m sure you get the picture.
I’m just having trouble getting traction and wondering what I can/should do better/different.
The one thing they were interested in finding out, is whether other financial institutions are using discussion forums and if so how. I was wondering you could help me find out if there are others, who they are and if they’d be willing to talk with me.
Great question. Of course, there’s no easy answers here, but lots we can discuss and learn around this.
In terms of finding people with experience on this, my first suggestion was using LinkedIn and particularly looking through LinkedIn Guide for Knowledge Workers, LinkedIn for Finding Expertise, and Searching for Expertise - LinkedIn Answers. This is in process. I’ll also reach out via twitter. If you have other ideas or if you are at a financial institution and are willing to have a discussion with this person, please drop me a comment/email.
Of course, there’s a lot of great information out there on this via eLearning Learning under terms like Discussion Forum, Collaboration in Discussion Forums, Discussion Forum Adoption, Benefits of Discussion Forums, Discussion Forum Case Studies. I also checked out Nancy White’s Communities and Networks site under Discussion Forums, Case Studies of Discussion Forums, and Community Building and Discussion Forums.
I found a lot of great stuff. Let me start with some of the ones that are probably more relevant to this particular inquiry:

What other resources or case studies would you point to around this topic?
Any thoughts or advice?
Help would be sincerely appreciated!
I’m involved in several discussions around how to use Wikis as part of learning solutions. I wanted to collect a few resources around this topic for use in these discussions. So, of course, I went to eLearning Learning and I looked at Wiki, Collaborative Learning with Wikis, Wikis and eLearning 2.0, Wikis Corporate eLearning, Social Learning with Wikis, Wiki Security and a few others. Here’s some of what I found:
