json-to-elan 0.1.17

The script reads a JSON file (or folder) and generates an ELAN file to match.

JSON to ELAN

The script looks in a folder, and generates an ELAN file to match each JSON file.

JSON format

It has been written for the JSON output from Huggingface ASR pipelines. Here's an example of the expected JSON format.

[
    {
        "text": "luanghan",
        "timestamp":
        [
            1.16,
            1.48
        ]
    },
    {
        "text": "ian",
        "timestamp":
        [
            1.56,
            1.7
        ]
    }
]

Basic usage

Put your JSON files somewhere easily accessible, eg in a data folder in your working directory. Install it. Use it by providing a path to your data.

pip install json-to-elan

from json_to_elan import make_elan 
make_elan(data_dir="content")

Using this in Colab?

To use this in Google Colab, upload your JSON files into the File browser. Then define the data directory as:

data_dir="/content"

Options

You can also set a different tier name from the default (which is "default").

The ELAN file gets a linked media file written, for which we assume that the media file is a WAV with the same name as the JSON file. If you want to change this to MP3, change the audio_format.

Here's an example:

make_elan(data_dir="content", tier_name="Words", audio_format="mp3")
