Part 2. AI Voices

FineVoice provides a wide range of built-in voices across multiple languages, professions, and age groups, plus a community-driven voice model library. The voice library offers diverse characteristics and styles, all available for trial in the FineVoice AI Voice Changer.

For custom needs, use our Voice Cloning and Voice Design tools to easily create the perfect voice for your project.

Currently, FineVoice has discontinued public access to community cloning models. Use of cloning models must comply with ethical and legal standards.

For best results, upload original audio that matches the source voice's language. Cross-language conversion is possible, but the output may retain the original accent and have lower quality, pronunciation accuracy, and naturalness.

Part 3. Quick Start

Step 1. Go to FineVoice

Select AI Voice Changer in the left menu bar.

Step 2. Upload Audio

Before converting your voice, provide an original audio input using one of two methods:

Upload an audio file:
Supports MP3, WAV, and M4A formats.
After uploading, the system automatically recognizes and uses the file for conversion.
Record audio:
Record directly with your microphone.
Once done, your recording will be used as the input for conversion.
* Record in a quiet environment for clearer audio and more natural results.

Step 3. Choose an AI Voice

Click "AI Voice" to open the selection window. Browse and filter FineVoice voices by age, gender, or keywords. Use the preview button to listen before choosing.

Step 4. Select a Voice Conversion Model

Pick the model that suits your needs. For best results, use the advanced OVC Max model.

Step 5. Generate Voice

Click "Generate". After conversion, the audio will play automatically. All converted voices are saved in your history.

Note

For more control over your generated audio, adjust the pitch to change its tone.

Part 5. Best Practices

Recommended:	Not Recommended:
Record in a quiet environment. If recording in a noisy setting, use the AI Voice Enhancer to improve audio quality first. The audio should ideally contain only one language. It's best to upload audio files with a single voice.	Using raw, unprocessed audio for direct voice conversion. Randomly mixing multiple languages. Mixing multiple speakers in one audio file.

Batch Audio Conversion

For converting many audio files with quality and consistency, use the Batch Audio feature to submit your request. Please provide:

1. Duration of your audio file

2. Target voice for conversion. (If the target voice is your own, please use the Voice Cloning feature to create your voice first)

3. Link to the audio file

4. Any additional requirements (e.g., file naming or format)

Note

Batch audio conversion is a premium service with additional fees. FineVoice subscribers get up to 100 hours free; beyond that, it's $0.50 per hour.

For batch conversion, we will process your audio files as follows:

1. Enhance the audio by removing noise, long silences, or extended silent segments.

2. Convert and save audio files in bulk as requested.

Once the conversion is complete, you will be notified by email and in-site message.

Part 6. Frequently Asked Questions

1. Why is AI voice conversion sometimes slow?

Long text/audio: Large inputs take longer to process.
Solution: Split into shorter segments and merge after generation.
Network/server delay: Poor connections slow uploads and processing.
Solution: Check your network or use it during off-peak hours.
High concurrent requests: Many tasks can slow down processing.
Solution: Use during off-peak hours.

2. Can I use it for commercial purposes?

Community models are for personal use only.
For commercial use, choose an official commercial or your own cloned model and follow copyright rules.

3. Why does the voice sound unnatural after adjusting pitch?

Excessive pitch changes can cause distortion or affect speed.
Solution: Adjust pitch moderately (±2~4 semitones) and use gradual changes with previews for larger adjustments.

4. Can I purchase additional characters when my quota runs out?

Yes, you can buy extra credits without upgrading your plan or re-registering.
