Usage Examples

Basic Translation

# Translate text
translate_text(
    text="Hello, world!",
    source_language="en",
    target_language="es"
)
# Returns: "¡Hola, mundo!"

# Auto-detect language
detect_language(text="Bonjour le monde")
# Returns: {"detected_language": "fr", "confidence_score": 0.99}

Batch Translation

# Start batch job
start_batch_translation(
    input_s3_uri="s3://my-bucket/documents/",
    output_s3_uri="s3://my-bucket/translated/",
    data_access_role_arn="arn:aws:iam::123456789012:role/TranslateRole",
    job_name="my-translation-job",
    source_language="en",
    target_languages=["es", "fr", "de"]
)

Smart Workflow

# Automated translation with quality validation
smart_translate_workflow(
    text="Hello, how are you?",
    target_language="es",
    quality_threshold=0.8
)

AWS Permissions

Required IAM permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "translate:*",
                "s3:GetObject",
                "s3:PutObject",
                "s3:ListBucket",
                "sts:GetCallerIdentity"
            ],
            "Resource": "*"
        }
    ]
}

Troubleshooting

1. Authentication Errors: Ensure AWS credentials are configured
2. Translation Failures: Check language pair support and text length limits
3. Batch Job Issues: Verify S3 permissions and IAM role configuration
4. Workflow Issues: Check workflow orchestrator in health check
