How to Build a Voice Translation App: Technical Aspects

It doesn't matter whether you want to build a voice translation app from the beginning or integrate voice translation components, the technology of the translation service is almost the same. The formula for voice translation has two components. It is as follows:

Microservices:

It is implemented on the cloud using cloud AI features to translate messages:

  • speech to text
  • cloud translation
  • convert spoken to written

Functions performed by microservices include:

  • Receives audio messages that have been encrypted.
  • Transcripts audio messages with Speech-to-Text API.
  • translates messages using a translation API.
  • Synthesizes the translated message with the Text-to-Speech API.
  • Stores the translated message in cloud storage.
  • Send the translated response back to the client.

Client App:

The client component records audio messages and subsequently downloads the translated messages from a cloud storage bucket.

Functions performed by the client app include:

  • Records audio messages with Speech-to-Text API.
  • Encodes the audio message.
  • Sends an HTTP request to the microservice with the encoded audio message.
  • Receives HTTP response in place of the translated audio message from the microservice.
  • The cloud storage sends a request to Bucket to receive the translated audio message.
  • Plays the translated audio message.

In addition to the technical aspects of voice translation app development, application development goes through several stages that are critical to meeting the needs of competing applications that meet the needs of the user.

  1. Market Research: This is the initial and probably the most important step when getting started with an application. With market research, you make predictions about the potential of the market, its trends, market developments, and your value proposition.
  2. Competitive Analysis: In parallel with market research, stakeholders conduct a competitive analysis to list popular names, reveal their users, user preferences, which features are most beloved, and more.
  3. Finalizing the Concept: Your idea may be too vague. Before market research, it may be outdated or unrealistic. A more optimal way to have a voice translation app concept is to rely on research data.
  4. Creating App Name and Logo: This voice translation should be easy to remember and eye-catching.
  5. Real-time translation design: Wrap your applications and features in a presentable and beautiful "package" that lets users love your app. Simple UI/UX and accessibility are priorities here.
  6. Gamification and attractive functionality: Add a fun part to your application to make your app unique.
  7. Marketing Plan: Support voice translation app development and deployment with a robust marketing plan to grab customers prior to app launch.
  8. Security Matters: Think about a robust security system for your app that will use cloud services and messaging technology.
