Vevo1.5

Vevo1.5

We present Vevo1.5, a versatile zero-shot voice imitation framework capable of modeling both speech and singing voices. This framework offers two key features:

1. Unified speech and singing voice modeling.
2. Fine-grained control over multiple voice attributes, including text, melody, style, and melody.

For a hands-on demonstration of Vevo1.5's capabilities, we invite readers to explore our accompanying blog post.

Pre-trained Models

We have included the following pre-trained models at Amphion:

The training data includes:

• Emilia-101k: about 101k hours of speech data
• Sing-0.4k: about 400 hours of open-source singing voice data as follows:

  Dataset Name	#Hours
  ACESinger	320.6
  OpenSinger	45.7
  M4Singer	28.4
  Popbutfy	23.8
  PopCS	11.5
  Opencpop	5.1
  CSD	3.8
  Total	438.9

• SingNet-7k: about 7,000 hours of internal singing voice data, preprocessed using the SingNet pipeline. The SingNet-3k is a 3000-hour subset of SingNet-7k.

Usage

You can refer to our recipe at GitHub for more usage details. For example, to use Vevo1.5, after you clone the Amphion github repository, you can use the script like:
