🚀 About Project

---

Speech recognition, also known as automatic speech recognition (ASR), computer speech recognition, or speech-to-text, is a capability which enables a program to process human speech into a written format. The Speako is a Natural Language Processing based project built on top of stack of technologies in order to transcribe the English voice based audio files of any accent. The project further provides the facility to user to provide the Urdu Translation of that transcribed text. Lastly, it also extracts Keywords from that transcribed text.

Features:

---

• 🤩 This project will let the users to transcribe there .flac or .wav audio file.
• 🥳 Translate the transcribtion into Urdu Language.
• 😋 Extract the Key points of text.

Model Selection Steps:

We selected four accurate working Transcription Models and peform evaluation to select the best performer among four of them.

• Facebook/wav2vec2-large-960h-lv60-self
• Facebook/wav2vec2-lv60-base
• Pytorch transformers model
• Deep search model by Mozilla

📈 Dataset:

• Audio clips of different English accents were collected several online resources.

🔩 Preprocessing Step:

• Sampled the Audio file at 16 KHz
• Removed any distortion or background noises from the audio

💭Evaluation:

These are the following evaluation metrics which were considered to select the best working model.

• Word Error Rate for each model
• Match Error Rate for each model
• Word Information Loss for each model
• Word Error Rate for each accent
• Match Error Rate for each accent
• Word Information Loss for each accent

All the evaualtion results and meta-data are logged in Neptune AI

Fine-Tuning Steps:

📈 Dataset:

• TIMIT: is a corpus of phonemically and lexically transcribed speech of American English speakers of different genders and dialects.

🔩 Preprocessing Step:

• Removed irrelivant features from English dataset.In our dataset: phonetic_detail , word_detail, dialect_region, sentence_type, speaker_id)
• Removed expressions like \ , \ ? \ . \ ! \ - \ ; \ : \ "
• Sampled the Audio file at 16 KHz

💭Evaluation:

• Use WER (Word Error Rate)

🎶 Training:

• TRANSFORMER: We use Transformers from huggnig face.

• Model Used: facebook/wav2vec2-large-960h-lv60-self

🔤 Translation

---

Supported Language:

URDU

• Translates the transcription into Urdu Language.
• Model Used: Helsinki-NLP/opus-mt-en-ur
• In future we will be adding a Pipeline channel to preprocess and generate direct results from it

📌 Keywords Extraction

---

• Text analysis feature that automatically extracts the most used important words from a transciption. It helps summarize the content of texts and recognize the main topics discussed.
• Model Used: KeyBERT

🔮 User Interface

---

• The UI of the project is built using Streamlit.
• It provides a responsive GUI presenation of the project with their respective model results.

🏭 Project Pipelining

---

• Inference Pipeline using ZenML
• Fine Tuning Pipeline for English ASR with Transformers
