The total cost depends on how long the model runs. It costs $0.000247 per second. Based on an average runtime of 21 seconds, each run costs about $0.005197. With a $1 budget, you can run the model around 192 times.

API & SDK

Create a Prediction

Send a POST request to create a new prediction. This will return a prediction ID that you'll use to check the result. The request should include your model inputs and API key.

Get Prediction Result

Poll the prediction endpoint with the prediction ID until the result is ready. The API uses long-polling, so you'll need to repeatedly check until you receive a success status.

Overview

 Kokoro 82M is a state-of-the-art text-to-speech model designed to produce high-quality and natural-sounding audio from text inputs. Kokoro 82M gives flexibility in voice selection, speed adjustment, and seamless control over the output. Kokoro 82M model is ideal for creating lifelike voiceovers, audio content, or any scenario requiring synthesized speech with precision and clarity.

Technical Specifications

  • Advanced Neural Architecture: Kokoro 82M leverages cutting-edge technology to analyze and synthesize text into natural speech.
  • Flexible Input Handling: Kokoro 82M supports text of varying lengths and complexities, ensuring consistent performance across use cases.
  • Voice Variety: Includes multiple pre-trained voices with distinct tonal qualities, offering diversity for different needs.
  • Speed Control: Kokoro 82M allows for dynamic pacing adjustments, enabling applications ranging from audiobooks to quick announcements.
  • High Fidelity Output: Kokoro 82M is designed to deliver clean, noise-free audio with clear enunciation and natural intonation.

Key Considerations

  • Text Structure Matters: Ensure that the input text is grammatically correct and well-structured to produce the best audio output.
  • Speed Extremes: Setting the speed parameter too high or low may affect intelligibility. Moderate adjustments are recommended.
  • Output Consistency: Shorter sentences and clear punctuation improve clarity and reduce the risk of unnatural pauses.

Tips & Tricks

  • Optimize Text: Avoid overly complex or ambiguous text. Break long sentences into smaller, clear segments for better results.
  • Speed Parameter:
    • For formal content, keep speed values moderate (e.g., 0.8 to 1.2) to ensure clarity and professionalism.
    • For dynamic or energetic outputs, experiment with slightly higher values (e.g., 1.3 to 1.5).
  • Voice Selection:
    • Use deeper tones for authoritative or serious contexts.
    • Lighter or more vibrant voices work well for engaging or casual content.

Capabilities

  • High-Quality Synthesis: Produces lifelike, natural-sounding speech that closely mimics human intonation and rhythm.
  • Flexible Parameter Control: Enables users to tailor outputs with adjustable speed and diverse voice options.

What Can I Use It For?

  • Voiceovers: Generate professional-grade voiceovers for videos, presentations, or tutorials.
  • Audiobooks: Create engaging and clear narrations for storytelling or educational content.
  • Announcements: Produce dynamic audio for announcements or alerts in public or private settings.

Things to Be Aware Of

  • Create a fast-paced announcement by setting the speed to 1.3 and using concise text.
  • Generate an audiobook snippet by selecting a steady speed (e.g., 1.0) and a calm voice.
  • Test how punctuation affects output by trying variations like pauses (commas) or emphasis (exclamation points).

Limitations

  • Text Complexity: While highly capable, overly intricate or poorly formatted text may result in suboptimal audio.
  • Speed and Comprehension: Extreme speed settings can hinder clarity and make the output difficult to understand.
  • Voice Availability: The pre-trained voices, while diverse, might not cover every niche use case or accent preference.

Pricing

Pricing Detail

This model runs at a cost of $0.000247 per second.

The average execution time is 21 seconds, but this may vary depending on your input data.

The average cost per run is $0.005197

Pricing Type: Execution Time

Cost Per Second means the total cost is calculated based on how long the model runs. Instead of paying a fixed fee per run, you are charged for every second the model is actively processing. This pricing method provides flexibility, especially for models with variable execution times, because you only pay for the actual time used.
