Get started with Voice
Are you ready for your AI Agent to start helping customers over the phone? This guide will help you get your AI Agent ready to smoothly and confidently help your customers in voice conversations.
This feature may not be included with your organization's subscription package. For more information, see Ada's Pricing page, or contact your Ada team.
Before you begin
Before you get started with Voice, take a moment to learn some background information. Then, you need to set up an account and phone number with Twilio.
Understand Voice's limitations
It's important to understand some limitations with Voice:
-
We currently only support calls in English.
-
The AI Agent will only allow callers to interrupt it when it’s collecting information from a caller.
Set up a Twilio account
Voice works by integrating a Twilio account with your AI Agent. Follow the below instructions to prepare an account and phone number to use with your AI Agent.
Your usage of Voice is subject to both applicable privacy and phone communication laws, and Twilio's policies. These may vary based on your location and industry. If you have any questions, please contact Ada's or Twilio's support.
-
If your organization doesn't already have one, set up an account with Twilio. For more information, see View and Create New Accounts in Twilio Console at Twilio's Help Center.
-
Set up a phone number with Twilio, using one of the following options:
-
Purchase a phone number through Twilio. For more information, see How to Search for and Buy a Twilio Phone Number from Console at Twilio's Help Center.
-
Port an existing phone number from another service provider to Twilio. For more information, see Porting a Phone Number to Twilio at Twilio's Help Center.
-
-
Submit your organization's toll-free phone number to Twilio for verification.
-
If you are using a toll-free number with your AI Agent and you want to be able to send SMS messages from it during a phone conversation, you will need to submit a Toll-Free Message Verification request to Twilio. For more information, see Toll-Free Message Verification for US/Canada at Twilio's Help Center.
-
If you are using a local number with your AI Agent and you want to be able to send SMS messages from it during a phone conversation, you will need to submit an A2P (Application to Person) 10DLC (10 digit long code) registration request to Twilio. For more information, see Programmable Messaging and A2P 10DLC at Twilio's Help Center.
-
After getting your phone number set up with Twilio, you can connect it with your AI Agent.
Connect your Twilio account with your Ada AI Agent
Once you have your Twilio account and phone number set up, you can put your account details into your AI Agent. In your Twilio account, you need to obtain your account string identifier (SID), and create an API key to use with Ada. Follow these steps to get them and put them into your AI Agent settings:
-
On the Ada dashboard, go to Channels > Voice, then go to the Configuration tab. Keep this page open as you go into your Twilio account to get your account details, so you can paste them in as you find them.
-
In your Twilio console, in your account info, find your Account SID. Your Account SID is a unique identifier that acts like a username when you're using Twilio's API. For information on how to find it, see Auth Tokens and How to Change Them at Twilio's Help Center.
-
On the Ada dashboard, under Twilio Configuration, paste your Account SID into the Twilio Account SID field.
-
In your Twilio console, create a new API key. Enter a name into the Friendly name field, set the Key Type to Main, and leave the other settings with their default values.
For information on how to create an API key, see API Keys and How to Change Them at Twilio's Help Center. When you create an API key, you get both a key and a secret. You can only view the secret once for security reasons, so make sure you save it in a safe place.
-
On the Ada dashboard, under Twilio Configuration, paste the API key into the Twilio API Key SID field, and paste the secret into the Twilio API Key Secret field.
-
Configure your AI Agent to use a phone number, or configure a SIP address to handle transfers between your AI Agent and your CCaaS provider. Your AI Agent can only use one or the other. Click a section to expand the full instructions.
For more information on how you can configure transfers either using the phone network or over the internet, see Integrate your voice AI Agent with your Contact Center as a Service (CCaaS) provider.
-
Click Save. After you have connected your AI Agent, the Phone toggle automatically switches on.
The configuration section of your AI Agent has some additional options you can set, but we'll cover those and what they mean in later topics.
Choose a speaking voice for your AI Agent
Choosing a speaking voice for your AI Agent is an important part of your AI Agent's branding. You can change your AI Agent's voice at any time to better fit your AI Agent's branding needs.
You can choose voices from two providers:
-
Google: Currently, we only offer Google voices that have US accents. If you want more information about the voices Google offers, see Supported voices and languages page at Google Cloud's documentation.
-
OpenAI: We offer all of the voices OpenAI offers. For information about these voices, see Text to speech at OpenAI's documentation.
While Google voices support SSML, which is the markup you can use to control how your AI Agent pronounces content in voice conversations, OpenAI voices don't. OpenAI voices are generally better at guessing how to pronounce content, but can sometimes struggle pronouncing content like long or complicated numbers. If you have terms that these voices don't pronounce as expected, consider spelling those terms out phonetically.
Each voice you can choose lists the provider as part of the voice's name. Keep these differences in functionality in mind as you select the one your AI Agent uses.
-
On the Ada dashboard, go to Channels > Voice, then go to the Speaking voice tab.
-
Under Speaking Voice, select a voice. Each time you select a different voice, your AI Agent automatically generates a preview of the text in the speech bubble so you can hear what it would sound like over the phone.
-
Optionally, in the text field, you can type in a text sample, like a message from your AI Agent, so you can hear your AI Agent read out a specific piece of your AI Agent content. Then, you can click the Play button to play the sample.
-
Click Save. your AI Agent immediately starts using the voice you selected for both internal testing and for any live voice content in your AI Agent.
Configure how long a caller can be silent before your AI Agent hangs up
You can choose how much time your AI Agent will wait for a caller to speak before it assumes the caller is gone and ends the call.
-
On the Ada dashboard, go to Channels > Voice, then go to the Configuration tab.
-
Under Maximum caller silence (seconds), enter the number of seconds you want your AI Agent to wait before hanging up.
-
Click Save.
Help your voice AI Agent understand special terms
Does your company use special terms like product or feature names, or acronyms that might be hard for your AI Agent to understand? Does your industry have specialized vocabulary your callers are likely to refer to? You can improve your AI Agent's chances of recognizing those terms by adding them into your AI Agent's vocabulary. That way, when a caller refers to them, your AI Agent can reply with accurate information, and provide accurate transcripts of the calls for your analysis.
-
On the Ada dashboard, go to Channels > Voice, then go to the Vocabulary tab.
-
Add, remove, or dig deeper into the terms in your list as required:
-
To add a new term, click New Term. A new row in your vocabulary table appears. Type in a term, then click Add term.
-
To delete an existing term, hover over its row and click the Delete button that appears.
-
To view all the conversations where callers used a term, beside that term, click View conversations.
