Translate language

If you haven't already done so, run amplify init inside your project and then amplify add auth (we recommend selecting the default configuration).

Run amplify add predictions, then use the following answers:

? Please select from one of the categories below
❯ Convert
Learn More
? What would you like to convert? (Use arrow keys)
❯ Translate text into a different language
Generate speech audio from text
Transcribe text from audio
? Provide a friendly name for your resource
<Enter a friendly name here>
? What is the source language? (Use arrow keys)
<Select your default source language>
? What is the target language? (Use arrow keys)
<Select your default target language>
? Who should have access?
Auth users only
❯ Auth and Guest users

Run amplify push to create the resources in the cloud

Working with the API

Here is an example of translating text. In order to override any choices you made in regards to target or source languages while adding this resource using the Amplify CLI, you can pass in them in directly as parameters as shown below.

func translateText(text: String) async throws -> String {
do {
let result = try await Amplify.Predictions.convert(
.translateText(text, from: .english, to: .italian)
print("Translated text: \(result.text)")
return result.text
} catch let error as PredictionsError {
print("Error translating text: \(error)")
throw error
} catch {
print("Unexpected error: \(error)")
throw error
func translateText(text: String) -> AnyCancellable {
Amplify.Publisher.create {
try await Amplify.Predictions.convert(
.translateText(text, from: .english, to: .italian)
.sink(receiveCompletion: { completion in
if case let .failure(error) = completion {
print("Error translating text: \(error)")
}, receiveValue: { value in
print("Translated text: \(value.text)")

As a result of running this code, you will see the translated text printed to the console.
