Amazon Lex V2

The Amazon Lex V2 bot service lets you create and host bots in AWS cloud.

Please refer to Amazon documentation for building your bot.

Here we will introduce some basic concepts needed to integrate your bot to VoiceAI Connect.

Basic concepts

Intents

Intents are conversation flows in Lex V2. An intent can be triggered with a pre-defined set of sentences.

For example, "Track a package" flow is an intent, which can be triggered with the following utterances:

• Where is my package

• I want to check my package location

• When will my package arrive

Activities

An activity is a control command sent to Voice AI Connect and not to the end user (e.g. Start recording, switch language etc.)

For more information on activities, see Sending activities to VoiceAI Connect

Disconnect event

At the end of the conversation, VoiceAI Connect can send a DisconnectionEvent to Amazon Lex V2. this is

is optional but can help identify a conversation in logs.

For more information on activities, see API runtime DisconnectionEvent

Notifications

A notification is a message sent from Voice AI Connect to the bot, but is not necessarily related to the current intent (e.g. no user input event). See Receiving the notification

Event names can be used in <angle-brackets> as sample utterances to trigger an intent, but to extract the data send with the event, a lambda is needed.

You can check the Receiving notifications from VoiceAI Connect to Lex V2 bot for a complete example.
