How to Create a Voice Translation App?

YEREVAN, Armenia - Aug. 3, 2023 - PRLog -- Today, we can do almost anything with our smartphones, and translation is no exception. From computer-assisted translation (CAT) tools to machine translation apps, there are hundreds of apps to choose from.

The core technology of real-time and voice translation solutions is machine translation. AI and machine learning have been changing the translation industry for a long time.

Voice translation simplifies the way speakers of different languages communicate. It is a software that can translate human speech from one language into another, and read aloud the translated text.

How Does the Voice Translation App Work?

The core features of voice translation are based on 3 technologies:

1.  Automatic speech recognition (ASR) – The app recognizes your voice and words and transforms them into a written text.

2.  Machine translation (MT) – The transformed text is then translated with a machine translation module.

3.  Voice synthesis (TTS) – The translated text is spoken in a target language.

No matter if you want to create a voice translation app from scratch or to integrate voice translation components, the technology of translation service is almost the same. In simple words, the formula of voice translation consists of two components. It is as follows:

Microservice

Microservice is implemented on the cloud using Cloud AI features to translate the message:

• Speech-to-Text
• Cloud Translation
• Text-to-Speech

Tasks performed by the microservice include:

1.  Receives encoded audio messages.

2.  Transcribes the audio message with the Speech-to-Text API.

3.  Translates the transcribed message with the Translation API.

4.  Synthesizes the translated message with the Text-to-Speech API.

5.  Stores the translated message in Cloud Storage.

6.     Sends the translated response back to the client.

Client app

On the user side, the client component records audio messages and later downloads the translated message from the Cloud Storage bucket.

Tasks performed by the client app include:

1.  Records the audio message with the Speech-to-Text API.

2.  Encodes the audio message.

3.  Sends an HTTP request to the microservice with the encoded audio message.

4.  Receives the HTTP response to the locale of the translated audio message from the microservice.

5.  Sends a request to the Cloud Storage bucket to retrieve the translated audio message.

6.     Plays the translated audio message.

How Much Does it Cost to Create a Voice Translation App?

The approximate voice translation app development cost is $25.000 – $30.000. The price is calculated based on minimum viable product features without post-release support and maintenance. Keep in mind that a voice translation app development cost depends on a number of factors, including the number and complexity of app features, the number of platforms, the development partner's expertise and location, etc.
