Project Overview

TLDR; Text extraction, transcription, punctuation restoration, translation, summarization and text to speech

The goal of this project is to extend the functionalities of Fabric. I'm particularly interested in building pipelines using utilities like yt as a source and chaining them with the | operator in CI.

However, a major limitation exists: all operations are constrained by the LLM context. For extracting information from books, lengthy documents, or long video transcripts, content may get truncated.

To address this, I started working on adding a summarization step before applying a fabric template, based on the document length. Additionally, I explored capabilities like transcripting, translating and listening to the pipeline result or saving it as an audio file for later consumption.

Examples

Listen to the condensed summary of a long Youtube video

yt --transcript url | tp --cb | tts

Read a web page summary

tp --ebullets https://en.wikipedia.org/wiki/Text_processing

Listen to the condensed French summary of a long English Youtube video

yt --transcript --lang en url | tp --cb --tr fr | tts

Save a book's wisdom as an audio file

tp my_book.txt --eb | fabric --p extract_wisdom | tts --o my_book_wisdom.mp3

Say "hello world!" in Chinese

echo "Hello world!" | tp --tr zh | tts

Translate a document to Spanish

tp doc_fr.txt --tr es > doc_es.txt

Generate a transcript in any language from a mp4 file. E.G.: from English to French

tp en.mp4 --tr fr

Listen in spanish a French audio file

tp fr.mp3 --tr es | tts

Convert a spanish audio book to a French audio book... and make an English transcript

tp es.mp3 --tr fr | tts --o fr.mp3 | tp fr.mp3 --tr en --o tr_en.txt

Extract ideas from an audio file, save them in a French text file

tp en.mp3 | fabric --p extract_ideas | tp --tr fr --o idées.txt

Perform OCR

Text Processing (`tp`)

Input (text or audio file)

tp receives from stdin or as first command line argument It accepts:

Text.
File path. Supported formats are: .aiff, .bmp, .cs, .csv, .doc, .docx, .eml, .epub, .flac, .gif, .htm, .html, .jpeg, .jpg, .json, .log, .md, .mkv, .mobi, .mp3, .mp4, .msg, .odt, .ogg, .pdf, .png, .pptx, .ps, .psv, .py, .rtf, .sql, .tff, .tif, .tiff, .tsv, .txt, .wav, .xls, .xlsx

tp accepts unformatted content, such as automatically generated YouTube transcripts. If the text lacks punctuation, it restores it before further processing, which is necessary for chunking and text-to-speech operations.

Transcription

Converts audio and video files to text using Whisper.

Summarization

The primary aim is to summarize books, large documents, or long video transcripts using an LLM with an 8K context size. Various summarization levels are available:

Extended Bullet Summary (`--ebullets`, `--eb` )

Splits text into chunks.
Summarizes all chunks as bullet points.
Concatenates all bullet summaries.

The goal is to retain as much information as possible.

Condensed Bullet Summary (`--cbullets`, `--cb`)

Executes as many extended bullet summary phases as needed to end up with a bullet summary smaller than an LLM context size.

Textual Summary (`--text`, `--t`)

A simple summarization that does not rely on bullet points.

Translation (`--translate`, `--tr`)

Translates the output text to the desired language. Use two letters code such as en or fr.

Usage

usage: tp [-h] [--ebullets] [--cbullets] [--text] [--lang LANG] [--translate TRANSLATE] [--output_text_file_path OUTPUT_TEXT_FILE_PATH] [text_or_path]

tp (text processing) provides transcription, punctuation restoration, translation and summarization from stdin, text, url, or file path. Supported file formats are: .aiff, .bmp, .cs, .csv, .doc, .docx, .eml, .epub, .flac, .gif, .htm, .html, .jpeg, .jpg, .json, .log, .md, .mkv, .mobi, .mp3, .mp4, .msg, .odt, .ogg, .pdf, .png, .pptx, .ps, .psv, .py, .rtf, .sql, .tff, .tif, .tiff, .tsv, .txt, .wav, .xls, .xlsx

positional arguments:
  text_or_path          plain text; file path; file url

options:
  -h, --help            show this help message and exit
  --ebullets, --eb      Output an extended bullet summary
  --cbullets, --cb      Output a condensed bullet summary
  --text, --t           Output a textual summary
  --lang LANG, --l LANG
                        Forced processing language. Disables the automatic detection.
  --translate TRANSLATE, --tr TRANSLATE
                        Language to translate to
  --output_text_file_path OUTPUT_TEXT_FILE_PATH, --o OUTPUT_TEXT_FILE_PATH
                        output text file path

Text To Speech (`tts`)

Listen to the pipeline result or save it as an audio file to listen later.

tts can also read text files, automatically detecting their language.

usage: tts.py [-h] [--output_file_path OUTPUT_FILE_PATH] [--lang LANG] [input_text_or_path]

tts (text to speech) reads text aloud or to mp3 file

positional arguments:
  input_text_or_path    Text to read or path of the text file to read.

options:
  -h, --help            show this help message and exit
  --output_file_path OUTPUT_FILE_PATH, --o OUTPUT_FILE_PATH
                        Output file path. If none, read aloud.
  --lang LANG, --l LANG
                        Forced language. Uses language detection if not provided.
