What Is Voice Translator App, and How Does it Work?
Before we proceed with voice translation app development, it is vital to know about it. So, what exactly is this real-time voice translator app?
Well, a voice translation app is a unique mobile application that translates your voice commands into another language you select. That means you can convert anything you speak in English to an Asian language, for instance, Chinese, in real-time.
But how does a voice translation app work?
A voice translator app uses advanced machine learning algorithms to interpret the message and generate a corresponding translation in another language.
Seems complicated? Here is a general overview of how a typical voice translation app might work:
- Speech Recognition: The voice translator app captures the spoken words using the microphone. The audio is then analyzed and processed to convert the spoken words into text using Speech Recognition. That is typically done using Automatic Speech Recognition (ASR) which uses deep neural networks to analyze the sound waves and produce text.
- Natural Language Processing: Once the message is converted into text, the voice translator app uses Natural Language Processing (NLP) algorithms to interpret the meaning of the words and sentences in the source language.
- Translation: The app then uses machine translation technology to generate a corresponding translation in the target language. That is typically done using statistical machine translation, neural machine translation, or a combination of both, depending on the app.
- Speech Synthesis: Finally, the translated text is converted into spoken words using Text-to-Speech (TTS) technology. The app then plays the translated audio back to the user.
Why are Companies Investing in Voice Translation App Development?
According to some trusted sources, the market of voice translation apps already surpassed $650 million in 2020. The market is further expected to reach $3 billion by 2027! Moreover, the Global Voice and Speech Technology market will generate a revenue of $22.9 billion by 2026.
Well, looking at the profitable market of voice translator app development, we can clearly see that the growing demand for enterprise mobility solutions and cross-country trades facilitated the growth of voice translator apps.
Additionally, a few more reasons also justify the exponential growth of voice translator apps in 2023. To name a few, we have:

Features play a crucial role in today’s competitive market. We all know there are countless options for people in a singular arena, and the voice translation app market is no exception. Besides the competitors mentioned above, many others can give you tough competition.
Hence, when designing a voice translator app, you need to consider the users’ needs and the features that will make the app easy to use and effective in translating languages. As a leading app development company, here we have listed some features that you should consider incorporating into your voice translator app:
The app should support multiple languages, including popular languages such as English, Spanish, French, Chinese, and Arabic. However, you can also use text-to-speech or speech-to-text options and add several other languages to your voice translator app.
Today’s era is about AI development services, and voice translation app is no exception. Your real-time voice translator app should have a robust voice recognition system to accurately recognize and translate the user’s spoken words. You can even use NLP services to further enhance the conversational capabilities of your voice recognition tool.
The app should be able to convert translated text into speech, making it easy for users to hear the translation. You must also incorporate the reverse of that, i.e., a speech-to-text conversion that can help users appropriately convey their message.
The app should have the ability to work offline, which is especially useful for users traveling abroad who may not have access to Wi-Fi or cellular data. That means your app could seamlessly assist users and help you promote your brand even during the most difficult times of zero internet connectivity.
The app should provide pronunciation assistance to users, helping them learn how to pronounce words in the target language correctly.
The app should include a phrasebook that contains commonly used phrases and sentences, making it easier for users to communicate in the target language. The saved words or phrases must also be highlighted in this feature.
The app should have customizable settings that allow users to adjust the font size, language preferences, and other settings to suit their needs. Besides, you should also allow your users to change their usernames, contact details, and email address in the app.
Integration with Other Apps
The app should be able to integrate with other apps, such as messaging apps or social media platforms, to make it easier for users to communicate in different languages. You can offer online payments, social sign-in, or even in-app communication functionalities with third-party integrations.

Not to mention, the task of hiring an elite app development team that has decade-long expertise in creating such apps can also be a daunting task for some companies. But here’s how you can make it a piece of cake by following some general steps:
Step 1: Requirements Analysis & Market Research
The first step to begin with your voice translator app development is to understand your requirements and determine the scope of your app and the languages you want to support. You will need to decide whether you want the translation done in real-time or if it will be a two-step process where the user records their speech, and then the app translates it.
Additionally, the main aim of developing the voice translator app must also be determined. For that, you can ask yourself questions like:
- Who is my target audience?
- How can they benefit from my voice translator app?
- What are other apps prevalent in the market?
- What are the top features of those apps liked by my target audience?
- What technology and resources will I need to develop an app?

Every app needs a solid monetization model to generate revenues during the initial period. Whether you generate revenues from third-party advertising, freemium models, or in-app purchases, there should be a perfect plan to monetize your app; else, there would be no good reason to launch your app.
Hence, you must explore the top monetization techniques for your voice translator app. An expert app development company can also help you choose the most suitable monetization model that fits your needs and helps you cater to your financial requirements.
