The Power of Text to Speech, Powered by Voice Recognition

“Hey, Siri…”

“Hi, Alexa…”

“OK, Google…”

Everywhere and anywhere we turn these days, Voice Recognition innovation is present. In our homes. On our phones. Even in our cars.

And for good reason. Voice Recognition is a powerful technology and tool that (most of the time) makes our lives easier, more productive, and quite literally listens to and (again, mostly) satisfies our wants and desires.

It’s by no means perfect, but Voice Recognition is not only here to stay, it’s only going to play a more prominent role in our lives than it already does.

One perfect example is something we most likely use every single day: Speech to Text (STT).

In fact, it’s become such an indelible part of our lives, we’d bet you’d be hard pressed to find a single person who’s “amazed” by this technology anymore.

Speech to Text is the very thing that enables you to send a message to, let’s say, your Mom using nothing but the magic of your own voice.

“Hey Siri, text Mom: Love you!” And then, voila, the words you just spoke into existence travel into the phone, are transformed into a text, which then moves through cell tower after cell tower all the way to dear ol’ mum.

Whoa. Pretty impressive stuff.

But there’s a lesser-known tool of Voice Recognition technology that’s just as (if not more) powerful, especially for contact centers. And if you’ve called into a contact center before, you’ve most likely experienced this tool for yourself.

It’s called Text to Speech, also known as TTS. Technically speaking, it’s a speech synthesis technology that translates written text into spoken words. Yes, the opposite of Speech to Text.

In this post, we’ll take a look at the power of TTS—specifically the benefits for contact centers. Agents and customers alike can and do benefit greatly from this capability, and it’s crucial we understand its value in today’s Voice Recognition world.

What is Text to Speech?

TTS was originally developed as a technology to assist the visually impaired, helping them to understand website content (the contents of websites are spoken aloud). Now, TTS is a common feature in most, if not all, websites, computers, tablets, phones, digital apps—you name it.

As we mentioned above, Text to Speech is a speech synthesis technology, meaning that it synthesizes spoken words from written text, on the fly, instead of playing back a pre-recorded message.

Think about our hypothetical text message to Mom from before. You sent it using Speech to Text. And with Text to Speech, Mom is able to play a spoken version of that text message without ever having to lay eyes on the original written message.

This is important to note because this is not an easy thing to do, especially with the English language. In English, there are so many words that have the same spelling, but also have different types of pronunciation, and very often, a different meaning altogether.

For example, let’s say you had texted Mom something different instead. Imagine you’d like to ask her about her famous chocolate chip cookie recipe.

“Hey Siri, text Mom: How much butter do I need?”

Now, this may seem like a simple text message, but think about the work that has to go on behind the scenes. Voice Recognition (both STT and TTS) technology needs to figure out if it should spell and pronounce the word “butter” like the ingredient you use to cook with, or the phrase “but her” which would make for a very strange text indeed.

Picture using STT to send your Mom a message that says “How much but her would I need?” and there’s no doubt at all that when it’s read to her via TTS, she’d be rightly confused.

But with the power of Voice Recognition, STT and especially TTS, the technology is working behind the scenes to calculate the different probabilities based on the context of your message, ultimately choosing the most likely spelling and pronunciation. Granted, it’s an imperfect approach, as we’ve all likely experienced, but for the most part, it does the job swimmingly.

Let’s take a closer look at TTS and its many benefits for contact centers.

The Power of TTS for Contact Centers

Mobile marketing is more important than ever in achieving customer satisfaction. Case in point: do you still have a landline? But we bet you most definitely have a cell phone.

With businesses and contact centers all wanting to improve the experience for their customers, cloud-based telephony platforms need to ensure they have the right technology to help bridge potential communication gaps—and make communication more fluid and seamless.

Text to Speech is a technology that does just that. Sure, it may not be the newest technology on the block. It might not be the shiny, new “innovative” feature in the latest platform update. But it can be incredibly valuable to take a deeper look at how this existing technology is being used in innovative ways today.

Let’s explore how contact centers are using TTS to improve their agent and customer experiences (and therefore agent and customer satisfaction), as well as delivering increased ROI for their bottom lines:

1. Interactive Voice Response (IVR): An IVR should have a powerful plugin option like Text to Speech that allows call flows to be configured using DTMF (dual tone multi frequency) keypress options, so responses can be recorded accurately for things like receiving customer feedback.

With Text to Speech, for example, contact centers are conducting surveys and getting higher customer response rates when compared to email or SMS. TTS enables the use of dynamic survey scripts that can be updated as needed instead of relying on traditional pre-recorded messages. Survey creators simply update the survey text by typing.

2. Expand Reach: By using Text to Speech, contact centers are reaching a larger customer base than ever before, opening up new communication opportunities that could otherwise not exist—with the visually impaired, for example.

Expanding on point #1 above, TTS also helps contact centers get more positive feedback by making it easier and more convenient for customers to deliver that feedback. Surveys can be sent to a larger group of customers, and the content of those surveys can be static or dynamic as needed.

3. Outbound Dialing: Contact centers use Text to Speech for outbound calls because it works faster and because it’s one of the most cost-effective ways to do outbound dialing. TTS phone calls automate the redundant process of having to dial thousands or even millions of calls per day without having to repeat the same thing over and over again.

With TTS, contact centers are triggering outbound dials for routine calls designed to let customers know about payment reminders, promotional offers, appointment times, and more—allowing human agents to take care of more high-touch, high-value calls. Not only does this improve experiences for customers, but it also helps to deliver more ROI.

4. SMS Campaigns: SMS marketing campaigns impose restrictions such as character limitations, country-specific regulations, and more. Contact centers use Text to Speech technology because it works in concert with those restrictions, and supplements the effectiveness of SMS campaigns by helping to amplify reach.

Because of TTS, you can create a text message and turn it into a call to any mobile phone or landline around the world. When the customer answers, they hear the spoken message. This allows you to stay in line with SMS compliance rules and reach the customer in an unexpected and more personalized way.

5. Many Languages: Building on the point above about expanding reach, TTS is making it easier for contact centers to reach customers in multiple languages across different countries. Messages can simply be typed and then translated into the specific language(s) you need, eliminating the need for one or more humans to speak and record the content with the accent of a native speaker.

As you can imagine, this could help you reach out to customers on a much more personal level. Put yourself in the customer’s shoes. Wouldn’t you rather have a company quite literally speak to you on your level and in your language?

6. More Human: Not only does TTS help contact centers reach out to customers in a more personalized way, it also makes the typical telephone call seem more human and interactive than the technology used to allow for. Text to Speech has come a long way in turning what was once a very robotic experience into one that feels more like sitting across from a friend and having a conversation.

The customer experience is all about the human touch, and Text to Speech is an unexpected but powerful way to add that touch to your communication approach.

7. Lower Operational Costs: Research shows that contact centers are reducing their operational costs by up to 70% using Text to Speech software, especially with regard to outbound dialing, and also with inbound dialing when powered by the right Interactive Voice Response (IVR) system.

This is because contact centers are able to reduce manual intervention by automating appropriate dialing processes and call flows with TTS. Millions of calls can be processed automatically, potentially allowing you to do more work with fewer agents, and certainly enabling your agents to work more effectively by focusing on the most important calls at hand.

8. The Cloud: With the help of the right telephony software, Text to Speech audio can be processed incredibly quickly and then uploaded automatically into cloud-based web platforms. No more complicated or lengthy updates needed.

This makes it easier for contact centers to reach more customers more efficiently with dynamic messages that can be updated or changed on the fly.

9. Reduce Errors: Contact centers are using TTS to listen to the text that has been inputted by customers, thereby reducing errors from agents and allowing for more accuracy—something that would otherwise be impossible without the use of Text to Speech technology.

With fewer errors from agents and more accuracy overall, you’re able to drive more efficiency where you couldn’t before.

10. Improve Contacts: Thanks to TTS, contact centers can reach customers in a more effective way. How? Because Text to Speech allows for customization of text according to campaign requirements; it’s possible to enter either dynamic text, static text, or a mixture of both as necessary for a given campaign.

More routine calls can be automated and implemented using a static message, whereas fluid messaging (promotional offers, for example) can be handled via dynamic text.

As you can see, Text to Speech technology may not be the newest, shiniest, or most talked about technology these days. But it has never been a more powerful part of the modern contact center than it is today.

Does your contact center employ TTS? Do you use it in the ways above to make the agent and customer experience better? To improve agent and customer satisfaction? To improve ROI for your company?

Innovation comes in many shapes and sizes. Not only that, innovation also evolves as time goes on.

We hope this article helps you understand more about Text to Speech technology.

Even more important than that, we hope it helps you to see how this “once-innovative” technology is being used in very innovative ways in today’s contact center environment.
