Speech Dataset Generator by David Martin Rius
This repository is dedicated to creating datasets suitable for training text-to-speech or speech-to-text models. The primary functionality involves transcribing audio files, enhancing audio quality when necessary, and generating datasets.
-
Dataset Generation: Creation of multilingual datasets with Mean Opinion Score (MOS).
-
Silence Removal: It includes a feature to remove silences from audio files, enhancing the overall quality.
-
Sound Quality Improvement: It improves the quality of the audio when needed.
-
Audio Segmentation: It can segment audio files within specified second ranges.
-
Transcription: The project transcribes the segmented audio, providing a textual representation.
-
Gender Identification: It identifies the gender of each speaker in the audio.
-
Pyannote Embeddings: Utilizes pyannote embeddings for speaker detection across multiple audio files.
-
Automatic Speaker Naming: Automatically assigns names to speakers detected in multiple audios.
-
Multiple Speaker Detection: Capable of detecting multiple speakers within each audio file.
-
Store speaker embeddings: The speakers are detected and stored in a Chroma database, so you do not need to assign a speaker name.
-
Syllabic and words-per-minute metrics
-
Multiple input sources: You can either use your own files or download content by pasting URLs from sources such as YouTube, LibriVox and TED Talks.

The main script speech_dataset_generator/main.py
accepts command-line arguments for specifying the input file, output directory, time range, and types of enhancers. You can process a single file or an entire folder of audio files.
Also you can use a youtube video or a youtube playlist as input.
python speech_dataset_generator/main.py --input_file_path <path_to_audio_file> --output_directory <output_directory> --range_times <start-end> --enhancers <enhancer_types>
-
--input_file_path
: (source) Path to the input audio file. Cannot be used with input folder. -
--input_folder
: (source) Path to the input folder containing audio files. Cannot be used with input_file_path -
--youtube_download
: (source) Link or links separated by space of youtube videos or playlists. -
--librivox_download
: (source) Link or links separated by space of LibriVox audiobooks. -
--tedtalks_download
: (source) Aggregate Ted Talks audio or video links by separating them with spaces. Copy these links directly from the Share button URL, in the "Download" section, where is MP4 and Audio. -
--output_directory
: Output directory for audio files. -
--range_times
: Specify a range of two integers in the format "start-end". Default is 4-10. Clarification: in the first instance, the ranges are determined by WhisperX. Therefore you cannot modify them, but when using this parameter you can narrow and filter the ranges. -
--enhancers
: You can use audio enhancers: --enhancers deepfilternet resembleai mayavoz. Will be executed in the order you write it. By default no enhancer is set. By now deepfilternet gives the best results when enhancing and denoising an audio. -
--datasets
: there are available extra dataset types: metavoice and librispeech. librispeech is in beta version. --datasets metavoice librispeech

This project uses Whisper, making it multilingual. Here you can see the current supported language list.
You can combine --enhancers. There are available "deepfilternet", "resembleai" and "mayavoz".
If you pass multiples those will be executed in the order that are passed. In the case you don't pass enhancers no enhancer will be used.
By default, no enhancer is used.
You can combine them all the enhancers in the input.
I suggest using deepfilternet for noisy audios. It is the one that gives the best results when denoising.
The output sound of resembleai sometimes can be a little distorted. So, it is not always a good choise. It can denoise and enhance. If you are combining deepfilternet and resembleai, you can disble resembleai denoising.
In the case of resembleai you can play with its parameters at audio_manager.py
solver = "midpoint" #There is "rk4", "euler" and "midpoint" by default
denoising = True
nfe = 128 #range from 1 to 128, if the output sounds like a cassete you can reduce this value
tau = 0 #range from 0 to 1, better if disabled
The pretrained model of mayavoz only works with a sampling rate of 16000. Only recommended if the input source is also at 16000 hz.
An input audio may not be used completely. Here some reasons:
- The range_times do not fit a transcripted segment.
- The segment has music or not enough quality (MOS under 3), even when enhanced.
If you are not using enhancers and the segments are being discarted because of bad quality you can try --enhancers argument with deepfilternet, resembleai, mayavoz or combine them. See examples section to learn how to use it.
You can use an input audio with multiple speakers and multiple genders. Each speaker will be separated into a fragment and from that fragment the gender will be identified.
There is an example audio in this project with this case. It is in ./assets/example_audio_1.mp3 You can try it without coding in speech_dataset_generator_example.ipynb
- Youtube
- Librivox
- Ted talks
- Store speaker embeddings in Chroma vector database
- Everything is inside main.py The code needs to be reorganized.
- Detect the speech speed rate for each sentence and add it to the csv output file. The metrics are words per minute (wpm) and syllables per minute (spm)

- Add a speech_dataset_generator_example.ipynb file with all available options applied to some noisy audios and good quality audios.
- https://github.com/Anvarjon/Age-Gender-Classification Finally, this won't be integrated as it is too imprecise and only works well with the trained dataset, but not with unseen samples.
- Still pending. There is an uploaded PyPi package but does not work yet. Got some issues setup.py because some of the required packages are not available in PyPi. I am still looking for a way to install those packages. So, by now install the package from requirements.txt or setup.py.
Generator of multiple types of datasets:
-
LJSpeech This is the default one. When you generate a new dataset a LJSpeech format is given. It still does not split by train/dev/test, but creates a metadata.csv
-
Metavoice-src Example of the dataset: https://github.com/metavoiceio/metavoice-src/blob/main/datasets/sample_dataset.csv
-
LibriSpeech Currently in development. Work in progress
-
Common Voice 11
-
VoxPopuli
-
TED-LIUM
-
GigaSpeech
-
SPGISpeech
-
Earnings-22
-
AMI
-
VCTK
For example, from LibriSpeech to Common Voice and vice versa, etc.
I have to look for a way to extract all the needed features for each dataset type. Also find the best way to divide the dataset into train, dev and test taking into account the input data provided by the user.
-
Generate datasets
-
Dataset converter
In case you do not have a gpu or you want to distribute this as a service.
runpod is a cloud GPU on demand. It has a good integration with python and docker. Also it has an affordable pricing.
- Explain how to create a storage in runpod
- Create a base install to the storage with a Pod
- Launch a serverless instance with a Docker instance of this project
- Call the serverless custom API endpoints to upload files, download generated datasets, convert datasets to other types of datasets, etc
This project uses several open-source libraries and tools for audio processing. Special thanks to the contributors of these projects.
