Chinese English Speech Dataset

About this dataset

1. Product Overview

A Chinese English speech database, totaling 649 hours and 516,051 sentences. Sample rate: 16,000 Hz; bit depth: 16 bits. Transcribed and annotated by professional linguists, and rigorously quality-checked, achieving a text accuracy rate of over 95%.

2. Speech Data Transcription

Transcribers transcribe the audio content based on what they hear, striving to ensure complete consistency between the written text and the spoken audio. General guidelines are as follows: 1) The transcription must exactly match the spoken content—no extra words, missing words, or errors. 2) Numbers should be spelled out in English (e.g., “one two three”), rather than using numerals (“123”). 3) English words should be capitalized with spaces between them, e.g., “W W W dot Google dot com,” “C E O.”
