# HOWTO To Create Training Set of GOAT Warren Buffett for Mozilla TTS

|
||
|
|
Use the `LiveRecorder` Firefox plugin to record from Youtube.
|
||
|
|
|
||
|
|
Convert from webm to audio-only ogg.
|
||
|
|
```
|
||
|
|
ffmpeg -i berkshire-1994.webm -vn -acodec copy ./berkshire-1994-00:00_10:00.ogg
|
||
|
|
```
|
||
|
|
|
||
|
|
Split by silence. This automated splitting of files is the killer app for command-line audio tools, imo.
|
||
|
|
|
||
|
|
```
|
||
|
|
sox ./berkshire-1994-00:00_10:00.ogg berkshire-1994-00:00_10:00-.wav silence 1 0.2 0.5% 1 0.2 0.5% : newfile : restart
|
||
|
|
```
|
||
|
|
|
||
|
|
Play with trimming (start and duration)
|
||
|
|
then when you narrow down the clip, you can use `sox` to trim.
|
||
|
|
This is where GUIs like Audacity are still better.
|
||
|
|
|
||
|
|
```
|
||
|
|
play ./berkshire-1994-00:00_10:00-149.wav trim 0:00 0:02.5
|
||
|
|
sox ./berkshire-1994-00:00_10:00-149.wav ./berkshire-1994-00:00_10:00-149a.wav trim 0:00 0:02.5
|
||
|
|
|
||
|
|
```
