Unraveling the lack of standardization in speech recognition data

Welcome to our blog post on the absence of standardization in speech recognition data! In this article, we will explore the reasons behind the lack of established standards in the realm of speech recognition. From current data standards in machine learning to the challenges faced in the audio data domain, we'll provide you with insights into this intriguing topic. Additionally, we'll introduce StageZero's audio annotation tool, designed to simplify data formatting and enhance annotation efficiency. Let's delve into the complexities surrounding speech recognition data standardization! 

Background and history

Standardization has played a significant role in various domains of machine learning. In computer vision, for instance, data standards like the COCO format have emerged as benchmarks for testing algorithms. However, the audio data domain presents a different scenario, with limited information sharing and standardization practices among companies and researchers. To gain a deeper understanding of data standardization in machine learning, you can refer to this page on datasets for machine-learning research

Current data standards in machine learning

Over the past decade, data standards have been established in certain areas of machine learning, particularly in computer vision. Researchers' published datasets have driven the emergence of standards, such as the widely used COCO format for bounding boxes. These standards serve as benchmarks for evaluating and comparing different algorithms within the computer vision domain.

Challenges in establishing audio data standards

In contrast to the established standards in computer vision, the audio data domain faces challenges when it comes to standardization. The reasons behind this can be speculative, but it seems that less information sharing occurs among companies regarding speech recognition data practices. Data, being a valuable asset, is often closely guarded by companies, creating barriers to open collaboration and standardization efforts. 

Emerging trends and formats

While there isn't a standardized output format for speech recognition data, some general trends can be observed. Output formats commonly vary between JSON, CSV, or proprietary formats, often requiring the development of custom converters.

Regarding annotations and transcriptions, variations still exist among companies and researchers. However, there are some prevailing trends, such as the use of text instead of numerical labels, marking non-verbal sounds (e.g., "umm") with special characters, and adding tags for foreign languages. On the file storage front, a simple standardization has emerged where audio recordings are accompanied by correspondingly named annotation files, be it in text, CSV, or JSON format.
