Legal transcription remains essential for accurately converting and preserving recorded legal proceedings or hearings into text format. Research shows that the rapidly growing service sector represents 30% of all business transcription and is expected to be worth over $3 billion worldwide by 2029.
For many law firms, law enforcement agencies and other clients looking for legal transcription, the big question is when it comes to comparing artificial intelligence (AI) and human-based transcription, which is better and more reliable?
On one hand, legal transcription done through AI has its merits, including affordability, accessibility and speed. But it is crucial to carefully evaluate the strengths and weaknesses of AI and human transcriptionists before deciding. AI transcription particularly stands out regarding cost-effectiveness and quick turnaround times. Let us discuss the strengths and weaknesses of both.
The Advent Of AI In Legal Transcription
The U.S. Bureau of Labor Statistics predicts legal captioning will expand by 9% over the coming years. AI-based legal transcription offers an affordable and accessible solution for users without specialized training. Law firms can benefit from AI transcription for bulk transcriptions, saving costs on hiring in-house transcriptionists.
However, the drawback lies in AI’s inconsistency in producing highly accurate transcripts, which is crucial for legal processes. Human transcriptionists are more reliable for maintaining data accuracy and formatting in critical documents like courtroom proceedings, depositions and sensitive contract negotiations.
A hybrid approach combining AI and human transcription can enhance efficiency and accuracy, but clear instructions, communication and quality control processes are necessary for optimal results in this collaborative workflow.
Striking A Balance: AI Versus Human Transcription
Even with all the AI advancements available today, automation cannot effectively or fully replace trained personnel in legal transcription services. A human-based process offers multiple nonnegotiable quality and reliability guarantees for the ultimate legal transcript. Benefits include:
1. Cost Of Transcripts
AI technology offers initial cost savings since no specialized training is required. However, AI transcripts often contain errors, necessitating additional reviews, especially for legal transcripts with critical documents. To ensure accuracy, this process can become more time-consuming and costly. On the other hand, despite potentially being more expensive due to a better understanding of legal contexts, human transcription eliminates the need for extensive rework.
2. Accuracy Of Transcription
The most accurate AI transcription tools have demonstrated an 86% accuracy rate. But greater accuracy is essential in specific contexts like legal proceedings, as errors can have significant consequences. Trained human transcriptionists possess cognitive abilities that surpass AI, enabling them to understand speech context and dialects, enhancing transcription accuracy.
However, minor transcript errors may not heavily impact scenarios such as general business meetings. Even AI-generated transcripts are often reviewed and edited by humans to ensure accuracy, particularly when it comes to specialized content, multiple-speaker situations or speech containing technical terminology.
3. Speaker Identification
When it comes to speaker identification, both human transcription and AI transcription present distinct advantages. Let’s explore them together:
Advantages Of Human Transcription
• Proper speaker identification: Humans excel at distinguishing different voices in legal recordings and accurately attributing each statement to the corresponding speaker. Maintaining a transcript’s reliability is crucial, particularly in legal matters where crosstalk can pose challenges for AI voice recognition software.
• Contextual understanding: Human transcriptionists can comprehend the context of speech including nuances, emotions and nonverbal cues.
• Adapting to accents and dialects: Human transcribers are skilled in adapting to terminologies, and they can recognize regional nuances and linguistic variations that automated systems may struggle with.
Advantages Of AI Transcription
• Speed and efficiency: AI transcription systems can quickly process and transcribe large volumes of audio or video recordings, providing a significant time-saving advantage.
• Cost-effectiveness: Especially for organizations or individuals with limited budgets, automated transcription services can offer a cost-effective solution compared to hiring human transcribers.
• Scalability: AI systems can efficiently handle high transcription requests, making them suitable for businesses with fluctuating transcription demands.
4. Background Speech
AI technology has made significant advancements in audio processing, including the creation of noise reduction algorithms. These algorithms can analyze audio recordings and suppress unwanted background noise to enhance the clarity of the primary speech signal.
At the same time, AI-powered noise removal techniques occasionally result in errors. However, I find that human transcriptionists are more able to use discretion to “filter out” such noise and make judgments to only transcribe relevant parts of the conversation.
5. Data Security And Confidentiality Agreements
When using cloud-based AI transcription, you’re counting on the app to secure your potentially sensitive recording and the final transcript in the cloud. But as these processes are automated, it might take little responsibility for the confidentiality of your files online. Therefore, in many cases, I believe a human-based transcription service can provide the data privacy guarantees you need, including transcriptionists signing confidentiality agreements.
That said, AI transcription can offer a level of confidentiality by operating on anonymized data, whereas human transcriptionists usually have access to personal information and can recognize speakers. In this way, AI transcription can help maintain privacy, keeping sensitive information separate from the output. However, AI systems are not foolproof, and unintentional identification is still possible.
The Future Of Legal Transcription
Undoubtedly, AI has had a transformational impact on many technology-driven processes and is constantly improving. While it does better than humans in areas like predictive analytics and big data, I find that it still often fails to meet user expectations regarding transcription.
A human-based process satisfies most of these expectations for applications with high data accuracy levels—including legal transcription. While considering the factors above, the decision regarding which process will continue to dominate legal transcription services in the future is still unpredictable.
