• This repo is for the paper: "Speech-to-Singing Conversion in an Encoder-Decoder Framework" by Jayneel Parekh, Preeti Rao, Yi-Hsuan Yang in ICASSP 2020.

You can setup a new conda environment with the environment.yml file (recommended). You can start with miniconda installation if you are completely unfamiliar with anaconda

conda env create -f environment.yml

You will need to download the dataset (NUS-48E), models weigths, and clone a repo for melody extraction to run this code.

• The NUS-48E dataset can be downloaded from this link. The downloaded dataset (folder named 'NUS_48E') should be saved inside this repository (current working directory).

• The model weights can be downloaded from here. You should place the complete folder (named 'models') in the 'output' folder of this repo.

• Download code for melody extractor system (by Li Su) here. You should extract the zip and place the folder named 'VocalMelodyExtPatchCNN-master' inside this repo (current working directory). After that you should move the file 'VocalMelodyExtPatchCNN-master/model3_patch25' with the other files of the repo (in the current working directory)

The first time you run the code, it will also organize the audio from NUS-48E in a dictionary. This can take up to 10-15 minutes.

You can currently

1. Compute LSD for different models on random samples generated from NUS-48E dataset (with the function eval_sys()).
2. Compute random predictions for multiple models on the NUS-48E data (function random_pred()).
3. Compute prediction of a model on any given speech, melody file (function eval())

Both functions eval_sys() and random_pred() have some common set of arguments:

• model_list: Specifies the list of models you want to compute results for. Eg. ['PMTL', 'PMSE']. Current available model options are 'PMTL', 'PMSE', 'B1'. 'B2'.
• n_samp: Number of samples for prediction.
• min_length: Minimum length of the input speech signal (in seconds). Default value is 1.0
• fld: List of singer folders from NUS_48E dataset for whom you want to conduct evaluation. Eg. ['ADIZ']. Default value is ['ADIZ', 'SAMF'].
• psongs: List of songs for evaluation, for each singer specified in fld. Eg. [['01', '18']]. Default value is [['18'], ['18']].
• random (Not available with random_pred() function): Denotes if input samples used for prediction are randomly selected from the generated samples. Default value is True

Arguments for function eval()

• net1, net2: Networks which you want to use for prediction
• speech_file_loc: Location of file containing speech
• melody_file_loc: Location of file to extract melody from
