Artificial intelligence is packed with surprises the moment you think we have got enough of it, and it knocks on your door with another power-packed feature that makes your life even more accessible. One such product is the AI-based voice assistant app. Since the year 2018, every smartphone, tablet, etc., comes with a voice assistant that serves your command related to the functionalities of that particular device. It’s fascinating when you can talk to technology, and it’s a reminder of the technological evolution.
With the help of AI-based app development, voice assistant apps are evolving and learning the way we behave online. You can ask them for a ton of information like weather, traffic status, call any of your contacts, etc. Voice assistant app development is transforming the way we interact with our devices. However, there are certain things that you can’t expect from these apps. Every pre-existing voice assistant can’t execute your every command. That’s where the Hound app comes into the picture. It is considered to be a real step into the future. It is one of the fastest and most intelligent voice assistants that the world has ever seen. In this blog, you will learn about how to create a voice assistant app like Hound.
What is Hound App, and How Does it work?
Hound is an AI-based voice assistant app that is developed by the company SoundHound. The company is based in Santa Clara, USA. The app is known as one of its kind despite the presence of many other voices based digital assistants in the market, such as Siri, Amazon Alexa, etc. It has only one drawback that it can be launched only from the app. Users can talk to the app, ask questions, and even make it perform various tasks. The success of this app reflects in the dedication of the company as it hired over 150,000 testers to enhance the service and user experience over the period of 8 months. The hound app has started the tie-ups with Yelp and Uber and allows users to fetch information about restaurants and hail a cab ride right from their app.
Despite these improvements, it’s still struggling to become the go-to voice interface for smartphones and tablets. The Hound app is extremely fast and can deliver real-time translations of sentences that you can ever imagine. Just like Google, Apple, Amazon’s voice assistants, you have to say “Ok Hound” to initiate hands-free requests.
Working of Hound App
The working of Hound App is almost the same as other voice assistant apps, except it outsmarts them. The core technology behind the app is natural language processing combined with machine learning and artificial intelligence. When users give a command to such an app, others translate what they spoke into text and figure out what they are trying to say, while Hound eliminates this step and directly deciphers the speech. Users can ask for a customized search; for instance, they can ask, give me a list of nearby restaurants, and exclude Pizza Hut. Apart from all its features, the app has a default screen that guides the users about its capabilities. However, it does not have direct access to the device’s software like Apple, Amazon, and Google; hence, it lacks the intimate user data to understand their preferences. SoundHound is determined to create various domains with the help of third-party APIs. Currently, it is using a weather domain, a hotel search domain delivered by Expedia, and a phone domain to execute the user’s query.

- Microphone arrays play the role of separating environmental noise and reverberations to understand the query better. To facilitate far-field voice recognition, you can use these microphone array algorithms. Spatial filtering and Beamforming are the most effective Microphone array algorithms.
- Automatic Speech Recognition or ASR performs the function of converting speech to text for the app to understand better. There are two approaches; the first one is Long Short Time Memory (LSTM) neural networks, and the other one is Phoneme to Graphene, which is implemented with Hidden Markov Model. However, the ideal approach involves performing a Digital Signal Processing step to improve the audio signal quality with the help of algorithms.
- Natural Language Understanding or NLU is often referred to as a complex AI problem, but it is required to understand what the user is asking and what the app has to search accordingly. For the purpose of app development like Hound voice assistant, a narrow and shallow NLU system is enough.
- Skill routing and execution takes the intent of the user along with all the extracted entities and performs the business logic, and fetches structured data such as XML, JSON, etc., from various external sources. This is also responsible for the implementation of voice HMI.
- Natural Language Generation or NLG gets the structured data such as XML, JSON, etc., and delivers back the human-readable text. It is pretty similar to NLU and can be complexed too.
- Speech Synthesis, which is also referred to as Text to Speech, gets the answer of a query in the text form and converts it into an audio signal that is later delivered to the user through the device’s speaker. There are two popular approaches of it that you can follow, Concatenation Synthesis and Statistical Parametric Synthesis. They can be used to set the intonation, tone, stress, and rhythm of the query’s output.
- Several APIs can be fruitful for the development process; some of the relevant APIs are Google Speech API, IBM Watson API, SpeechAPI, Speech to Text API, Text-to-Speech API, Rev.AI API, ReadSpeaker API, Speech2Topics API, Siri API, and Wit API.
Your app development team should be well-rehearsed and aware of all the advancements in the field of artificial intelligence. Whether you hire a freelance team or a complete app development company, check for the client reviews and their previously made products. However, the team required for AI-based app development would be the same as any development team, but the specializations will be different.
A project manager with a deep knowledge of AI should be preferred to look after the complete progression of the project. An AI app developer with a verified experience is required to develop the app. However, the number of app developers would vary as per the complexity of the project. A QA expert is needed to verify the quality of the development. A testing engineer is needed to mark out all the bugs and errors in the app’s code and performance.
Return of Investments and a profitable business model is a crucial factor while building any project. Ultimately it all boils down to revenue generation. In terms of Voice assistant app development, there is not much scope for integrating business models, but here are some popular ones.
