WhisperSpeech: An Overview

WhisperSpeech is an ambitious project aimed at pioneering the field of speech synthesis. The project's goal is to create a model equivalent to Stable Diffusion but in the domain of speech – promising powerful capabilities and easy customization. The project operates with a commitment to Open Source code and the use of properly licensed speech recordings, ensuring safety for commercial applications.

Key Features and Updates

WhisperSpeech is currently utilizing the English LibreLight dataset for model training and aims to expand to multiple languages in its forthcoming release, with support for languages like Whisper and EnCodec.

Progress Report as of January 18, 2024

The project showcases the ability to mix languages within a single sentence, with English project names flowing smoothly into Polish speech. They highlight:

Whisper Speech
Collabora
Laion
Jewels

Additionally, they provide a sample of voice cloning using a speech by Winston Churchill, demonstrating the technology's advanced capabilities.

Progress as of January 10, 2024

The team reports on a new SD S2A model that is notably faster and maintains high-quality speech output. They included a voice cloning example utilizing a reference audio file.

Progress as of December 10, 2023

The update included samples of English speech with a female voice and a Polish speech sample with a male voice.

Older updates have been archived, indicating a progression and commitment to continual improvement.

Downloads and Roadmap

Downloads available include pre-trained models and converted datasets. The roadmap proposes gathering a more extensive emotive speech dataset, exploring generation conditioning on emotions and prosody, establishing a community-driven collection of freely licensed multilingual speech, and training finalized multi-language models.

Architecture and Recognition

The architecture involves several components:

AudioLM: Not described in the text but likely a component of the overall speech synthesis framework.
SPEAR TTS: Likely another component of the framework or a technology used in conjunction with WhisperSpeech.
MusicGen: Possibly related to generating music or controlling prosody in speech.
Whisper: Used for modeling semantic tokens through OpenAI's Whisper encoder block.
EnCodec: Handles modeling of acoustic tokens, delivering audio quality at reasonable bitrates.
Vocos: A vocoder pretrained on EnCodec tokens, enhancing audio quality.

Icon Library: A comprehensive set of icons provided by '@carbon/icons', suitable for mobile interfaces.

Getting Started with Carbon for React Native

To start using Carbon for React Native, you should first install the package using a package manager like npm or Yarn:

npm install -S @carbon/react-native
# or
yarn add @carbon/react-native

For iOS applications, you need to run pod install inside the ios directory of your React Native project.

Additionally, you'll need to ensure the following dependencies are installed and up to date:

@carbon/themes
@carbon/icons
@carbon/icon-helpers
react-native-svg
react-native-webview

Recommended Settings and Configuration

Carbon for React Native recommends certain configuration settings, such as adding the font assets to the react-native.config.js file and setting android:windowSoftInputMode="adjustPan" in your Android app to improve user experience.

Usage: React Native Components and Theming

The Carbon for React Native package makes using components straightforward. For instance, to use a Button component, you would import and implement it as follows:

import { Button } from '@carbon/react-native';

<Button kind="primary" text="My Button" onPress={() => {}} />;

The system also includes functions to work with themes and colors:

import { getColor } from '@carbon/react-native';

const styles = StyleSheet.create({
  example: {
    padding: 16,
    color: getColor('textPrimary'),
    backgroundColor: getColor('background'),
  },
});

Overriding Themes and Contributing

Carbon for React Native allows developers to override the default themes to customize color schemes and fonts according to their branding needs. Developers can also contribute to the system by following the Carbon Design System's contributing guide.

Licensing and Community

Carbon for React Native is released under the Apache-2.0 license, ensuring that it can be freely and reliably used in commercial projects. Furthermore, developers are welcome to the community and are encouraged to contribute. There is a continuous integration (CI) workflow in place to ensure that all contributions meet the required standards. Additionally, developers can chat and collaborate on Discord.

In summary, Carbon for React Native is a powerful tool for implementing the Carbon Design System in mobile applications, providing a wide range of components, customization options, and community support to create cohesive and user-friendly designs.

Marker: A Superior Document Conversion Tool

Overview

Marker is a software that converts PDF, EPUB, and MOBI files into markdown format. It is designed to be significantly faster than nougat, provide more accurate conversions, and have a lower risk of hallucinations (incorrect or fabricated content that doesn't exist in the source material).

Key Features

Support for various PDF documents, particularly optimized for books and scientific papers.
Capable of removing unwanted artifacts such as headers and footers.
Can convert many mathematical equations into LaTeX format.
Formats code blocks and tables effectively.
Compatible with GPU, CPU, or MPS hardware.

How Marker Works

The Marker operates through a pipeline of deep learning models to process documents:

Text Extraction: It extracts text and performs Optical Character Recognition (OCR) using heuristics and Tesseract when necessary.
Layout Segmentation: The layout segmenter analyzes the document's format.
Column Detection: To handle multi-column documents.
Nougat Model: Marker utilizes nougat for part of its processing.
PDF Postprocessor: Cleans up the document after conversion.

Marker encountered a [repetition] in 1.5% of pages during testing, but it outperforms nougat in terms of speed and general-purpose usage, particularly with equation blocks.

Performance Comparison

Marker has been benchmarked against nougat, showing that it is 10x faster and uses less VRAM.

Community and Support

Marker has a community on Discord where users can interact and share their experiences.

Limitations

While Marker is powerful, it does face some challenges:

Fewer equations converted to LaTeX compared to nougat.
Inconsistent whitespace and indentation management.
Not all lines may be correctly joined.
Better support for languages similar to English; limited support for Asian languages.
Optimized for digital PDFs, so heavy OCR isn't its forte.

Installation and Setup

For Linux

The installation involves cloning the Marker repository, running a few scripts for dependencies like Tesseract and Ghostscript, and setting up the environment with poetry.

For Mac

The Mac installation process is similar but utilizes Homebrew for installing requirements and then proceeds with setting up poetry and configuring the local environment.

Usage Guidelines

Configuration

Prior to use, certain environment variables must be set, such as TORCH_DEVICE, INFERENCE_RAM, and ENABLE_EDITOR_MODEL, which can be customized within local.env and settings.py.

Converting Files

Marker can convert single files or batch convert multiple files. For batches, one can define several parameters like worker count, RAM usage per task, maximum number of pages, and default language.

Running Benchmarks

Marker provides a benchmark.py script to compare its performance against naive text extraction and nougat.

Commercial Usage

Due to licensing restrictions of underlying models like Layoutlmv3 and nougat, Marker is intended only for non-commercial usage.

For inquiries or issues regarding commercial restrictions, users can contact Marker's support via marker@vikas.sh.

Acknowledgements

Marker's development has been greatly influenced by open-source models and datasets provided by various organizations, including Meta, Microsoft, IBM, and Google.

Conclusion

Marker showcases an advancement in document conversion technology, offering fast, accurate, and reliable conversion of complex documents into markdown format. Nevertheless, it has some current limitations and restrictions concerning commercial use, which are being addressed.
