Data Characteristics & Limitations

⚠️ Important notes about data quality:

• Language: Content is primarily in Hindi and Hinglish (Hindi-English mix)
• Speaker variety: 17 distinct speakers across 17 episodes (not accurate)

Loading the Dataset

Using Hugging Face Datasets

from datasets import load_dataset

# Load from local Parquet file
dataset = load_dataset("parquet", data_files="train.parquet", split="train")

# Or load from Hugging Face Hub (if uploaded)
dataset = load_dataset("username/shark-tank-india-s1-tts", split="train")

# Iterate through samples
for sample in dataset:
    audio = sample["audio"]
    text = sample["text"]
    speaker_id = sample["speaker_id"]

    # Audio data can be accessed as:
    audio_array = audio["array"]
    sampling_rate = audio["sampling_rate"]

    # Use for TTS training...

Using Pandas

import pandas as pd

# Load Parquet file
df = pd.read_parquet("train.parquet")

# Explore the dataset
print(df.head())
print(f"Dataset shape: {df.shape}")
print(f"Unique speakers: {df['speaker_id'].nunique()}")
