Echo/Alexa Product Line
Amazon Echo Amazon Tap Amazon Echo Dot Echo enabled third party devices

What is Amazon Echo
• Hands-free speaker you control with your
voice.
• Echo connects to the Alexa Voice Service to
play music, provide information, news, sports
scores, weather, and more - instantly. All you
have to do is ask.
• Echo has seven microphones and beam
forming technology so it can hear you from
across the room - even while music is playing.
• Echo is also an expertly tuned speaker that
can fill any room with 360° immersive sound.
• When you want to use Echo, just say the
wake word "Alexa" and Echo responds
instantly.

Echo Details
• Echo needs to be always connected to power outlet (does not have battery)
• Always need to be connected to net (through a high speed router) to be functional
as all of it’s power comes from cloud.
• Echo is always on – using wake word (by default “Alexa”) wakes it up

Echo Dot and Tap
• Has a tiny speaker, otherwise same
as Echo – so called Echo Dot
• Typically you'll hook Dot up to your
own audio setup (via out jack
or Bluetooth), so you can use Alexa
with your existing speakers.
• The tiny speaker won't output much
audio - it's only for Alexa voice
feedback (which, again, requires Wi-
Fi).
• Portable Bluetooth and Wi-Fi
enabled speaker
• Unlike Echo, Tap is wireless & must
be set into the included cradle in
order to charge
• The Tap isn't an always-on, so you
can't say "Alexa" to wake it and
instead need to press the
microphone button on the front.

What is Alexa
• Alexa is the brain behind Alexa devices like Echo, Dot, Tap and other 3rd party
Alexa enabled devices.
• Alexa is the voice service that powers Amazon Echo, provides capabilities, or skills,
that enable customers to interact with devices in a more intuitive way using voice.
• Alexa is similar to Siri, Cortana or ok google/google home.
• Alexa runs in the cloud – the device streams info to Alexa service running in the
cloud.
• Amazon is continuously improving and enhancing Alexa - so it is always getting
smarter. The more customers use Alexa, the more she adapts to speech patterns,
vocabulary, and personal preferences.

Skills
• Functionalities or capabilities built by third party to extend core skills of Alexa and
build new customer experiences.
• Think of Skill in Alexa as an app in mobile parlance
• Skill logic could be developed in any language & web stack (Java, Node.js, Python,
C#, Go, PHP)
• Skills could be hosted in cloud (AWS, Azure, Google Cloud Platform, Heroku, PCF,
other PaaS or IaaS) or in your data center / on prem. (internet reachable)

Type of Skills
• Out of the box skills
developed by
Amazon that comes
pre-built when you
purchase the device
• Time, Weather,
News, Wikipedia,
Traffic, Music, …
BUILT IN SKILLS
• Anything that is not
covered by Built in
Skill
• Food delivery,
Request Taxi, Game,
CUSTOM SKILLS
• Skills to control
smart home devices
like lights,
thermostats, router,
freeze, car, any
smart home
automation/IOT
device
SMART HOME SKILLS
• For building Flash
Briefing skills which
delivers pre-
recorded audio clips
and text-to-speech
(TTS) updates to
customers.
• Examples include
updates from
popular
broadcasters and
blogs, recent
headlines, weather
• Each Flash Briefing
skill contains one or
more content feeds.

Interaction Model

Intents
INTENTS
• What the user specifically wants the skill to do. You map the user's spoken intents
to intents your service can handle.
• Intents are specific requests, questions or commands. e.g. "Alexa, Ask Alarmy to
set the alarm for 7:30 am."
• All Skills have intents – a skill at min should have one intent
• Skills typically have multiple intents
• Each intent maps to a method in your code that is called
E.g. CapitalOne has built a Alexa skill for their customers which support these intents
• Account balance
• Last transactions
• Credit card statement (amount due, payment date)
• Pay credit card bill

Intents (Cont’d)
BUILT IN INTENTS
• Intents that are often used are already defined by Amazon
• Allows users to engage with different skills in a consistent way
• Using built-in intents for these types of common actions is useful for several
reasons:
• You do not need to spend the time writing sample utterances for the intent.
• Users can use common, consistent phrases to access the intent across skills. This makes it
easier for users to work with your skill.
• Your skill gets the benefit of any future updates to the Alexa service that improve recognition
and utterances for these intents.
• E.g. -
• StopIntent, CancelIntent, HelpIntent, YesIntent, NoIntent, RepeatIntent, StartOverIntent, …

Slots
SLOTS
A variable passed to the intent – like when to set alarm, city for weather etc.
BUILT IN SLOT TYPES
Amazon.Date, Amazon.Duration, Amazon.Number, Amazon.US_City,
Amazon.Four_Digit_Number, Amazon.Time, Amazon.US_State,
Amazon.US_First_Name, …
CUSTOM SLOT TYPES
Used for items that are not covered by Amazon’s built-in set of types and is
recommended for most use cases where a slot value is one of a set of possible
values. Examples –
• List of signs (Horoscope)
• List of non US cities
• List of services (Ola Prime, Ola Micro, Ola Mini, Ola Auto, Ola Shared)
• List of stock exchanges (NASDAQ, London stock exchange, NSE, Tokyo stock exchange, Shanghai)

Parsing Invocation Name, Intent and Slots
Alexa, ask Schneider for nearest distributors in London
Alexa, ask DigiSure for status of my last vehicle claim
Alexa, ask MyWeather for temp (No slot type specified – city is
inferred as current location of user)
Wake
Word
Invocation
Name
Intent Slot
Wake Word could be configured to
Alexa, Amazon or Echo

Solution Elements
VUI
• Design Voice User Interface (VUI) & Invocation Name
• Decide Intents to be supported, Develop Intent Schema (.json)
Speech
• Define sample phrases / sample utterances
• Define slot types
Build
• Build your code (Node / Python / Java)
• Host your code (AWS Lambda / Other PaaS options)
Portal
• Define your app/skill in amazon developer portal
• Define interaction model, link your skill to code hosted in cloud
Test
• Test your skill – echoism.io emulator and device (Echo/Dot/Tap)
• Submit your skill for certification
Before you start, refer Voice Design Handbook and Voice Design Best Practice

Voice User Interface (VUI)
• Design the voice experience – voice experiences are different than web & mobile
experience
• Think about a core functionality that you want to build first – your skill should do
one thing very well, rather than attempting multiple things
• Later add additional functionality iteratively
• User empathy

Invocation Name
• Invocation name is how Alexa identifies the capability a user wants
• Often this is the name if the Skill, though they could be different.
• Should uniquely identify your skill, should be catchy and easy to remember and b/w
1 – 3 words (Guidelines)
Alexa, ask Schneider for nearest distributors in London
Alexa, ask DigiSure for status of my last vehicle claim

Other settings in Amazon Dev Portal
• Contains other settings like Skill type (Custom / Smart Home / Flash Briefing),
Name, Language supported, App Id (auto generated) etc

Handling Requests Sent by Alexa
• Verify that the Request is Intended for Your Service
• To do this validation, every request sent by Alexa includes an application ID. You
can check this ID to ensure that the request was intended for your service.

Request Types
• Launch Request
• Intent Request
• Session Ended Request
• Session Started
• AudioPlayer Requests
• PlaybackController Requests

Request Types
LaunchRequest
• Your service receives a LaunchRequest when the user invokes the skill with the
invocation name, but does not provide any command mapping to an intent.
• User: “Alexa, talk to Daily Horoscopes” / “Alexa, open Daily Horoscopes”
• Skills that just do one thing (such as telling a joke), the service can take action
without requesting more info from user. Services that need more info from user
may need to respond with a prompt.
• Maps to onLaunch() in Java SDK
• A LaunchRequest always starts a new session

Request Types
IntentRequest
• Your service receives an IntentRequest when the user speaks a command that
maps to an intent.
• The request object sent to your service includes the specific intent and any defined
slot values.
• Maps to onIntent() in Java SDK
• An IntentRequest can either start a new session or continue an existing session,
depending on how the user begins interacting with the skill:

Request Types
SessionEndedRequest
• Your service receives a SessionEndedRequest when a currently open session is
closed for one of the following reasons:
1. The user says “exit”.
2. The user does not respond or says something that does not match an intent defined in your
voice interface while the device is listening for the user’s response.
3. An error occurs.
• Maps to onSessionEnded() in Java SDK

Request Types
AudioPlayer Requests and PlaybackController Requests
• Your service receives the AudioPlayer and PlaybackController requests only if you
are using the AudioPlayer interface to stream audio.
• Alexa sends AudioPlayer requests to notify your service about the current status of
the playback.
• The PlaybackController request are sent when the user interacts with the device
using hardware buttons, such as a remote control.

Voice design best practices
Getting Information from the User
• Make It Clear that the User Needs to Respond
• Don’t Assume Users Know What to Do
• Clearly Present the Options
• Keep it brief
• Avoid Overwhelming Users with Too Many Choices
• Offer Help for Complex Skills
• Ask Only Necessary Questions
• Obtain One Piece of Information at a Time
• Use the Amazon Alexa App to Enhance Discovery
https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/alexa-skills-kit-voice-design-best-practices

Voice design best practices
Presenting Information to the User
• Make Sure Users Know They are in the Right Place – Set the right context while
responding
• Present Information in Consumable Pieces – Use pagination where more
information need to be presented
• Write for the Ear, not the Eye – make the interaction as verbal as possible, users
should feel that they are talking with another human being
• Avoid Technical and Legal Jargon
• Use Text-to-Speech Effectively
• Use SSML where required

SSML - Speech Synthesis Markup Language
Tags Description Usage
Speak Root element of an SSML document. When
using SSML with the Alexa Skills Kit,
surround the text to be spoken with this tag
<speak>
This is what Alexa sounds like without any SSML.
</speak>
audio Lets you provide the URL for an MP3 file
that the Alexa service can play while
rendering a response.
<speak>
Welcome to Car-Fu.
<audio src="https://carfu.com/audio/carfu-welcome.mp3" /> You
can order a ride, or request a fare estimate. Which will it be?
</speak>
break Represents a pause in the speech. Set the
length of the pause with the strength or time
attributes.
<speak>
There is a three second pause here <break time="3s"/>
then the speech continues.
</speak>
p Represents a paragraph. This tag provides
extra-strong breaks before and after the tag.
<speak>
<p>This is the first paragraph. There should be a pause
after this text is spoken.</p>
<p>This is the second paragraph.</p>
</speak>
phoneme
s Represents a sentence. This tag provides
strong breaks before and after the tag.
This is equivalent to:
- Ending a sentence with a period (.).
- Specifying a pause with <break
strength="strong"/>.
<speak>
<s>This is a sentence</s>
<s>There should be a short pause before this second
sentence</s>
This sentence ends with a period and should have the same
pause.
</speak>

SSML - Speech Synthesis Markup Language
Tags Description Usage
say-as Describes how the text should be
interpreted. This lets you provide additional
context to the text and eliminate any
ambiguity on how Alexa should render the
text. Indicate how Alexa should interpret the
text with the interpret-as attribute.
• characters, spell-out: Spell out each letter.
• cardinal, number: Interpret the value as a cardinal number.
• ordinal: Interpret the value as an ordinal number.
• digits: Spell each digit separately .
• fraction: Interpret the value as a fraction. This works for both
common fractions (such as 3/20) and mixed fractions (such as
1+1/2).
• unit: Interpret a value as a measurement. The value should be
either a number or fraction followed by a unit (with no space in
between) or just a unit.
• date: Interpret the value as a date. Specify the format with the
format attribute.
• time: Interpret a value such as 1'21" as duration in minutes
and seconds.
• telephone: Interpret a value as a 7-digit or 10-digit telephone
number. This can also handle extensions (for example,
2025551212x345).
• address: Interpret a value as part of street address.
w Similar to <say-as>, this tag customizes the
pronunciation of words by specifying the
word’s part of speech.
