Tutorial

Overview

This tutorial walks you through the complete process of uploading an audio file, getting it transcribed, and translated into multiple languages using the Tiro API.

Prerequisites

Valid Tiro API key
Audio file (MP3, WAV, M4A)
Max file size: 500MB
Max duration: 4 hours

Step 1: Create a Voice File Job

Start by creating a job with your desired transcription and translation settings:

curl -X POST https://api.tiro.ooo/v1/external/voice-file/jobs \
  -H "Authorization: Bearer $TIRO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "transcriptLocaleHints": ["ko_KR"],
    "translationLocales": ["en_US"]
  }'

async function createVoiceFileJob() {
  const response = await fetch('https://api.tiro.ooo/v1/external/voice-file/jobs', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.TIRO_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      transcriptLocaleHints: ['ko_KR'],
      translationLocales: ['en_US']
    })
  });
  
  if (!response.ok) {
    throw new Error(`Failed to create job: ${response.status}`);
  }
  
  const job = await response.json();
  console.log('Job created:', job.id);
  console.log('Upload URL:', job.uploadUri);
  
  return job;
}

        }
    )
    
    response.raise_for_status()
    job = response.json()
    
    print(f'Job created: {job["id"]}')

  "id": "b2d1ab32-3fe2-4201-b0b4-391abdbaa023",
  "uploadUri": "https://storage.example.com/upload/signed-url"
}

Step 2: Upload Your Audio File

Upload your audio file to the provided signed URL:

# Upload audio file to the signed URL (replace UPLOAD_URI with the uploadUri from Step 1)
curl -X PUT "$UPLOAD_URI" \
  -H "Content-Type: audio/mpeg" \
  --data-binary @/path/to/your/audio.mp3

async function uploadAudioFile(uploadUri, audioFile) {
  const response = await fetch(uploadUri, {
    method: 'PUT',
    body: audioFile,
    headers: {
      'Content-Type': audioFile.type || 'audio/mpeg'
    }
  });
  
  if (!response.ok) {
    throw new Error(`Upload failed: ${response.status}`);
  }
  
  console.log('File uploaded successfully');
}

// For Node.js with file system
const fs = require('fs');

async function uploadAudioFileNode(uploadUri, filePath) {
  const fileBuffer = fs.readFileSync(filePath);
  
  const response = await fetch(uploadUri, {
    method: 'PUT',
    body: fileBuffer,
    headers: {
      'Content-Type': 'audio/mpeg'
    }
  });
  
  if (!response.ok) {
    throw new Error(`Upload failed: ${response.status}`);
  }
  
  console.log('File uploaded successfully');
}

def upload_audio_file(upload_uri, file_path):
    with open(file_path, 'rb') as audio_file:
        response = requests.put(
            upload_uri,
            data=audio_file,
            headers={'Content-Type': 'audio/mpeg'}
        )
    
    response.raise_for_status()
    print('File uploaded successfully')

func uploadAudioFile(uploadUri, filePath string) error {
    file, err := os.Open(filePath)
    if err != nil {
        return err
    }
    defer file.Close()
    
    req, _ := http.NewRequest("PUT", uploadUri, file)
    req.Header.Set("Content-Type", "audio/mpeg")
    
    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        return err
    }
    defer resp.Body.Close()
    
    if resp.StatusCode != http.StatusOK {
        return fmt.Errorf("upload failed: %d", resp.StatusCode)
    }
    
    fmt.Println("File uploaded successfully")
    return nil
}

fun uploadAudioFile(uploadUri: String, filePath: String) {
    val file = File(filePath)
    val headers = HttpHeaders().apply {
        contentType = MediaType.parseMediaType("audio/mpeg")
    }
    
    val resource = FileSystemResource(file)
    val entity = HttpEntity(resource, headers)
    
    val response = restTemplate.exchange(
        uploadUri,
        HttpMethod.PUT,
        entity,
        String::class.java
    )
    
    if (response.statusCode.is2xxSuccessful) {
        println("File uploaded successfully")
    } else {
        throw RuntimeException("Upload failed: ${response.statusCode}")
    }
}

Step 3: Notify Upload Completion

Tell the API that the upload is complete:

curl -X PUT "https://api.tiro.ooo/v1/external/voice-file/jobs/$JOB_ID/upload-complete" \
  -H "Authorization: Bearer $TIRO_API_KEY" \
  -H "Content-Type: application/json"

async function notifyUploadComplete(jobId) {
  const response = await fetch(
    `https://api.tiro.ooo/v1/external/voice-file/jobs/${jobId}/upload-complete`,
    {
      method: 'PUT',
      headers: {
        'Authorization': `Bearer ${process.env.TIRO_API_KEY}`,
        'Content-Type': 'application/json'
      }
    }
  );
  
  if (!response.ok) {
    throw new Error(`Failed to notify upload: ${response.status}`);
  }
  
  console.log('Upload notification sent');
}

def notify_upload_complete(job_id):
    response = requests.put(
        f'https://api.tiro.ooo/v1/external/voice-file/jobs/{job_id}/upload-complete',
        headers={
            'Authorization': f'Bearer {os.getenv("TIRO_API_KEY")}',
            'Content-Type': 'application/json'
        }
    )
    
    response.raise_for_status()
    print('Upload notification sent')

func notifyUploadComplete(jobId string) error {
    url := fmt.Sprintf("https://api.tiro.ooo/v1/external/voice-file/jobs/%s/upload-complete", jobId)
    
    req, _ := http.NewRequest("PUT", url, nil)
    req.Header.Set("Authorization", fmt.Sprintf("Bearer %s", os.Getenv("TIRO_API_KEY")))
    req.Header.Set("Content-Type", "application/json")
    
    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        return err
    }
    defer resp.Body.Close()
    
    fmt.Println("Upload notification sent")
    return nil
}

fun notifyUploadComplete(jobId: String) {
    val headers = HttpHeaders().apply {
        set("Authorization", "Bearer $apiKey")
        contentType = MediaType.APPLICATION_JSON
    }
    
    val entity = HttpEntity<String>(headers)
    
    restTemplate.exchange(
        "https://api.tiro.ooo/v1/external/voice-file/jobs/$jobId/upload-complete",
        HttpMethod.PUT,
        entity,
        String::class.java
    )
    
    println("Upload notification sent")
}

Step 4: Poll for Job Completion

Monitor the job status until processing is complete:

# Check job status (poll until status is COMPLETED or FAILED)
curl -X GET "https://api.tiro.ooo/v1/external/voice-file/jobs/$JOB_ID" \
  -H "Authorization: Bearer $TIRO_API_KEY"

# Example response:
# {
#   "id": "job_abc123",
#   "status": "COMPLETED",
#   "fileUploadedAt": "2024-01-01T12:00:20Z",
#   "processStartedAt": "2024-01-01T12:01:00Z",
#   "processCompletedAt": "2024-01-01T12:02:30Z"
# }

async function waitForJobCompletion(jobId) {
  let delay = 2000; // Start with 2 seconds
  const maxDelay = 30000; // Max 30 seconds
  const maxAttempts = 60; // 30 minutes max
  let attempts = 0;
  
  while (attempts < maxAttempts) {

          }
        }
      );
      
      if (!response.ok) {
        throw new Error(`Failed to get job status: ${response.status}`);
      }
      
      const job = await response.json();
      console.log(`Job status: ${job.status}`);
      
      if (job.status === 'COMPLETED') {
        console.log('Job completed successfully!');
        return job;
      }
      
      if (job.status === 'FAILED') {
        throw new Error(`Job failed: ${job.errorMessage || 'Unknown error'}`);
      }

Step 5: Retrieve Results

Once the job is completed, fetch the transcript and translations:

# Get transcript
curl -X GET "https://api.tiro.ooo/v1/external/voice-file/jobs/$JOB_ID/transcript" \

curl -X GET "https://api.tiro.ooo/v1/external/voice-file/jobs/$JOB_ID/translations/en_US" \
  -H "Authorization: Bearer $TIRO_API_KEY"

# Get transcript paragraph summary
curl -X GET "https://api.tiro.ooo/v1/external/voice-file/jobs/$JOB_ID/transcript/paragraph-summary" \

Step 6: Understanding Paragraph Summaries

The Paragraph Summary feature provides intelligent content summarization that helps you quickly understand the key points from your audio files.

What are Paragraph Summaries?

Paragraph summaries are automatically generated overviews of your transcript or translation content, broken down into logical sections. Each summary provides:

Concise Overview: Key points from each paragraph in markdown format
Language-Specific: Summaries generated for both transcript and translations
Structured Content: Easy to parse and integrate into your applications

Example Response

When you fetch paragraph summaries, you’ll receive a response like this:

{
  "jobId": "job-123",
  "locale": "ko_KR",
  "summary": [
    {
      "type": "markdown",
      "content": "### 회의는 프로젝트 진행 상황을 점검하고, 다음 단계에 대한 계획을 수립하는 데 중점을 두었습니다."
    },
    {
      "type": "markdown", 
      "content": "### 팀원들은 각자의 담당 업무에 대한 현재 상태를 보고하고, 발생한 이슈들에 대해 논의했습니다."
    }
  ]
}

When are Summaries Available?

Transcript and Translation Summaries: Available after job completion (COMPLETED status)
- COMPLETED means all processing is finished: transcript, translation (if requested), and paragraph summaries for both
Processing Time: Summaries are generated asynchronously, usually within 30-60 seconds after the main processing

Polling Best Practices

Exponential Backoff Strategy

Start delay: 2 seconds (processing takes time to start)
Growth factor: 1.2x (gentle increase)
Maximum delay: 30 seconds (avoid overwhelming the server)
Maximum attempts: Based on expected processing time

Job State Transitions

Processing Time Guidelines

File Duration	Expected Processing Time	Recommended Poll Interval
< 5 minutes	30-60 seconds	Start: 2s, Max: 10s
5-30 minutes	1-5 minutes	Start: 5s, Max: 20s
30-120 minutes	5-15 minutes	Start: 10s, Max: 30s
> 2 hours	15-30 minutes	Start: 30s, Max: 60s

Common Issues & Solutions

Upload Failures

Issue: 413 Payload Too Large
Solution: Check file size (max 500MB) and compress if needed

Processing Failures

Issue: Low audio quality
Solution: Ensure sample rate ≥8kHz and minimal background noise

Timeout Issues

Issue: Job doesn’t complete within expected time
Solution: Increase timeout for longer files, check job state for errors
