your own, you are absolutely right. Any mobile
app development company can create an app like
these without much hassle. They can easily
voice-enable their devices as it is only about
speech to text, a query parser, a pipeline, a
rules engine, and a pluggable architecture along
with open APIs. Why apps like Alexa are so
famous? There are a plethora of reasons for its

  response. How simple it is!
• Fascinating Children get lured by the functions
  these apps are bestowed with, hence they used it
  a lot.
• What technologies are used in Mobile Assistants?
• Speech to text (STT) engine In this, the users
  voice is converted into text, the voice may be of

Text to speech (TTS) engine This engine can
convert text to speech, and it is highly useful
when the user is occupied in some other
work. Tagging With this, the voice assistant
can understand what the user is trying to
say. Noise reduction engine This engine aids in
canceling out the external environment noise,
otherwise there will be too many stimuli that an
app will have to process. Voice biometrics This
authentication process helps an app to understand
that it is particularly your voice. User
interface it comprises of two parts, the voice
and the call out.

screen. Speech compression engine This can
compress the voice of the users so it can reach
the server faster. How to develop a voice
assistant app like Alexa? There are mainly three
methods that mobile app development services
deploy for building a voice assistant app- Junior
method which involves the integration of voice

And, the last method is building a voice
assistant from scratch and then integrating it
into the mobile app. Junior method This method
involves the integration of trusted technology
within an existing app. For this purpose, you
need to get a kit and then integrate it within an
app. The kit is used to define the intents as
types of requests, and then clarifies the types
and you have to group it into domains. This is
how the junior method works. Middle method This
method is suitable for those who have knowledge
of machine learning.
