No-code Voice Quickstart with Twilio Studio

Navigate to the sign up page to sign up for a free Twilio trial account.

• When you sign up, you'll be asked to verify your personal phone number. This helps Twilio verify your identity and also allows you to send test messages to your phone from your Twilio account while in trial mode.
• Once you verify your number, you'll be asked a series of questions to customize your experience.
• Once you finish onboarding, you'll arrive at your project dashboard in the Twilio Console . This is where you'll be able to access Twilio Studio, find a Twilio phone number, and more.

The first step to using Studio is to create a Flow. A Flow is a visual representation of your application, just like a flowchart you might draw when planning how your application works. The difference is this Flow is actually functional!

To create a Flow:

1. Navigate to the Studio Flows section in the Console.
2. Click Create new Flow . If you've already created a Flow before, click the + icon underneath the Flows heading to create a new Flow.
3. Give your new Flow a name, then click Next .
4. After you've named your Flow, you'll see a list of possible templates you can use. For the purposes of this Quickstart, select Start from scratch , then click Next .

Now for an express tour of the Studio interface and its components! After you've created a new Flow, you'll see the Flow's Canvas. The Canvas is the space where you build your applications when using Studio. On the Canvas, you'll see the Trigger Widget. The Trigger Widget tells Studio when to start or "trigger" your Flow and every new Canvas includes one. On the right side of the Canvas, you'll see the Widget Library where you can find all the available Widgets. Widgets are the building blocks of a Studio Flow and perform the functions that make up your application.

Now that you're familiar with the Studio interface and have a new Flow ready to go, it's time to start using Widgets to build your application! You'll create a system that automatically responds to an incoming call.

To respond to an incoming call, you'll need the Say/Play Widget. The Say/Play Widget allows you to play a recorded message, dictate text to a user, or play DTMF tones on a call. Use this Widget to say or play information to the user before any subsequent action. From the Widget Library on the right, click and drag the Say/Play Widget onto the Canvas.

In order for Studio to know when to respond, you need to tell it when to trigger your Flow. Since you want Studio to trigger this Flow when it receives a phone call, you'll click the red dot underneath Incoming Call on the Trigger Widget and drag it to the Say/Play Widget to connect them. Now when Studio receives a phone call, the Flow will trigger and execute whatever is connected to the Incoming Call transition—in this case, the Say/Play Widget.

Next, you'll configure the Say/Play Widget. With the Widget selected, the Widget Library will transform into the Inspector Panel where you can adjust the Widget's settings. Enter a name in the Widget Name field. The name can be whatever you like; however, please note the name must begin with a letter and cannot contain spaces. Use an underscore (_) to separate words instead.

The Say or Play Message or Digits field specifies the three ways you can respond to callers: generate text-to-speech audio from your typed message (Say), play a prerecorded message from an audio file (Play), or have the system read digits (Digits). For this Quickstart, choose "Say a message" from the dropdown options.

Enter the message you'd like callers to hear in the Text to say field and select a language from the Language dropdown. Then select a Message voice from the dropdown and specify the Number of loops you want to play.

Your Flow should now look like this:
