Even though nothing can compare to human emotions when speaking, Text-to-Speech technology has improved considerably in the last few years.
We even dare to say that it is pretty difficult to detect when a voice is natural or computer-generated.
Creating voice guides for a telephone system in your language can be expensive and delayed.
For this reason and contributing to the community, we have decided to create this blog article and provide all the resources to start your own set of voice guides automatically.
For this guide, we will use the TTS tools from Microsoft® Azure™, which currently possesses more than 270 neural voices in over 100 languages with their variants.
Azure also provides a free plan that gives us up to 500,000 characters per month. It’s enough to create up to 9 Voice Guide sets for VitalPBX per month.
One of the most significant advantages of using this technology is that you can have a unified voice type for your system voice guides, record your own IVRs, personalized messages, and much more.
It will make your PBX feel more professional.
As part of our contribution to the community, we will provide the following throughout this blog article:
First, we need to create a free Azure account.
You will need to have a valid credit card. You can proceed by going to the following URL, https://azure.microsoft.com.
Press the “Free Account” button.
Then, select the “Pay as you go” option since you will need a credit card to create the API Key, just in case you exceed the allowed monthly quota.
Afterward, click on “Get Started.” Here you can use an existing email account or create a new Outlook one. Then, follow the on-screen steps and make your Azure account.
Now that you have your account created, you can proceed to make your API Key to use TTS from our Application.
Azure Portal
Next, we head over to the Azure Portal to create our API Key, https://portal.azure.com/#home.
Create a Resource
Click on the “Create a resource” option and look for the “Speech” resource. Then, click on the “Create” Button.
Now, click on “Review + create.”
To finish, click on “Create” and you will be taken to the following screen.
Now, click on “Go to resource” and click on “Keys and Endpoints.”
We now have our API key, which we will use on our Application. Select Key 1 and copy it.
Now, you can download our TTS converter application to a Windows PC here, https://downloads.vitalpbx.com/apps/AzureTTSSetup.msi and proceed to install.
When you start the Application, you will be asked for your API key.
You can download the following texts, ready to be converted to speech, from the following links as an additional collaboration.
To use the TTS Application, we will briefly explain the functionalities.
So, as you can see, you can easily create your different voice guides affordably and quickly.
Though this may sound natural, as we mentioned initially, it is still challenging to emulate human expression and emotion accurately and dynamically.
So, hiring a voice actor will always be a more natural and realistic approach, depending on your time and budget.
We recommend our good friend Allison Smith if you want IVRs and messages with the same voice we use for our English Voice Guides, https://www.theivrvoice.com/.
