Take for example the keyword term "Maine", recordings with the following words may return as hits because they have the same sound as "Maine": "mainstream", "main", "mane".The automatic transcription method uses a speech recognition engine comprised of a language model, an acoustic model, and a dictionary. The models and dictionary work together to evaluate the recording's sounds and create a text transcript. A major strength of automatic transcription is that it generates a text transcription of the recording that can provide benefits beyond keyword search. With a transcript, reviewers can read the contents of the recording instead of having to listen to them, speeding up the review. This is also helpful if the legal team is still developing its keyword list and is not certain what content to search for. The models and dictionary may need to be manually adjusted to achieve acceptable results, making this method more complicated to implement than phonetic searching. Legal teams today utilize both phonetic searching and automatic transcription methods, however the automatic transcription method is better poised for future innovation. Advanced text analytics techniques such as text categorization (predictive coding), clustering, and conceptual search have been helping increase review efficiency and reduce legal spend for many years now and these same techniques can be applied to audio recordings, provided that the reviewing legal team has a text transcript. Text categorization could help answer questions like:· Which recordings should be reviewed first?· Can recordings that are likely irrelevant be outsourced to lower cost review teams or excluded from review altogether?· How much is review going to cost?Compliance teams could use text categorization in conjunction with clustering, concept search and sentiment analysis to flag and review communications that trigger risk areas or portend litigious activities, particularly for consumer action or product liability.ASR technology is helping legal teams implement more effective audio review strategies to comply with requests from regulators and other parties. A strategy that uses keyword search, enabled by ASR, can help target the right recordings to review and reduce the cost to review them. Keyword search is a step in the right direction but it is just the first step. As with email, additional analytics will be required to address growing data volumes. Soon there will be even more effective ways to target the most critical audio recordings for review so that legal teams can prioritize their understanding of the merits of the case, tied to key custodians and communications, and spend less time sifting through unorganized volumes of content which have less relevance to the case. Starting to sound familiar?A few years ago, a similar concern centered around structured data. How do you identify what you need, extract it without corruption and integrity loss, review it and produce it? What are the pitfalls and where is the solutions base? These were all questions discussed in the White Paper from the Richmond Law Journal. The technology and knowledge to facilitate the management of audio in e-discovery ­ the next wave of communication relevant to dispute resolution­is here, begging one question.... what's next?Jim VintASR technology is helping legal teams implement more effective audio review strategies to comply with requests from regulators and other parties
