Each recording was done with two mics, here we used the mic1 recordings. We chose sentence 23 for every speaker because it's generally the longest one to pronounce.

We select clips from the "conversational" files. For each pair of "kind" and channel (ex04-ex01_laughing, channel 1), we find one segment with at least 10 consecutive seconds of speech using VAD_segments.txt. We don't include more segments per (kind, channel) to keep the number of voices manageable.

The name of the file indicates how it was selected. For instance, ex03-ex02_narration_001_channel1_674s.wav comes from the first audio channel of audio_48khz/conversational/ex03-ex02/narration/ex03-ex02_narration_001.wav, meaning it's speaker ex03. It's a 10-second clip starting at 674 seconds of the original file.

Licensing:

• degaulle-2.wav: comes from the Appeal of 18 June, recording here. I don't understand how the license here works exactly, but I think it's safe to assume this recording is in the public domain since it's from 1940.
• ex04_narration_longform_00001.wav: comes from the Expresso dataset, so CC-NC
• p329_022.wav: comes from VCTK, so CC BY 4.0

The others are our own recordings and you may use them as CC0.

For each of the 107 speakers, we use the middle 10 seconds of the freeform_speech_01.wav file. Additionally, we select two speakers, p003 (female) and p031 (male) and provide speaker embeddings for each of their emo_*_freeform.wav files. This is to allow users to experiment with having a voice of a single speaker with multiple emotions.
