What is does 'p' mean in Alan Studio example scripts?

This is a name of the variable that references an object you can use to call Alan Studio SDK methods. It also contains data for a user voice session and other contextual information. You can use any name for this variable.

This object has:

• Slot values for intents, for example: intent("$(A cat|dog|pig)", p => p.play("You say " + p.A)).
• play: a method to playback voice responses.
• state: an object for storing context data.
• userData: an object for storing user data during the current dialog session.
• auth: an object that accepts configuration from the client (mobile or web). Typically, it can be used for passing authorization data for external services.
• You can return a value from the current context by calling p.resolve(value).

How do I catch unrecognized voice commands?

To see the list of commands that have not been recognized, do either of the following:

• Open Alan Studio logs and click the Unrecognized filter option.

If you want to catch the utterance as the user pronounces it, you can use the Record intent audio option. In Alan Studio, go to the Integrations section and in the button settings section, enable this option. With this option enabled, you will see the play icon to next to an unrecognized command in Alan Studio logs. Click this icon to listen to the intent audio.

I get an error when downloading Alan Client SDK files

Check the Internet connection to your device and your computer.

I get the minSDK error on Android. How do I fix it?

The minimum possible Android SDK version required by the Alan Android SDK library is 21. If the version in your project is lower, you may encounter an error of this type: AndroidManifest.xml Error: uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [:alan_voice]. To fix it, open the ./android/app/build.gradle file, under defaultConfig, locate minSdkVersion and change the version to 21.

I get permissions errors on iOS. What should I do?

In iOS, the user must explicitly grant permission for an app to access the device microphone and camera. The Info.plist file of the app must contain NSMicrophoneUsageDescription and NSCameraUsageDescription keys with string values explaining how the app uses this data.

To add these keys, go to Info > Custom iOS Target Properties, add the Privacy - Microphone Usage Description and Privacy - Camera Usage Description permissions to the list and provide the descriptions for them. For details, see iOS Developer documentation.

Why does the Alan button request microphone permissions after every page refresh in iOS browsers?

By default, the browser is configured to ask you about granting camera and microphone permissions. To allow the microphone usage for Alan permanently, to the left of the address bar in the browser, tap aA > Website Settings. In the Settings window, under Microphone, change the permission to Allow.

This setting is available in iOS 13 and later.

How do I allow the microphone usage for a website viewed locally?

If you add the Alan button to a webpage or website viewed locally, for example, for debugging purposes, the browser will require you to allow microphone access every time you activate the button. To allow microphone access permanently, in Safari, go to Safari > Preferences > Websites, select Microphone and change the microphone permission to Allow.

Security and privacy

Does Alan record my conversations?

Alan does not record or store your conversations audio data. Alan does store the Speech to Text commands and responses from your app’s usage, which is entirely private to you and inaccessible to Alan employees and any third-party engines.

Alan technologies

What is SLU?

Spoken Language Understanding (SLU) is a voice processing technology designed to work with the error-prone output of Automatic Speech Recognition (ASR) instead of written text, like chatbots.

What is the Domain Language Model?

The Domain Language Model is a unique procedure Alan uses for training our Speech Recognition software to better recognize the specialized language of your app, dynamically adapting to your users' conversational style.

What is an intent?

An intent is a voice command the user says to receive a voice response or perform some action in an app.

What is an entity?

An entity is a specific part of speech or text holding data such as name or height. Each entity is part of an intent and conveys a set of information to the developer, for example, date, location and so on.

What is a context?

A context is the situation in which a conversation occurs. Contexts are a cornerstone in Alan’s conversational design as they dictate the flow of the conversation, much like in the real world, where different contexts may provide different meanings to the same sentence. In Alan Studio, developers can create unique context functions to specify the steps of the dialog and create interactive multi-stage conversations.

Billing

What is an interaction?

An interaction is a user's utterance associated with Alan's reply.

What is a user?

A unique user is a device from which the user connects to the voice assistant in your app. That is, if the user initiates several dialog sessions from the same device, he or she will still be considered a unique user.
