Can you convert OPUS to text?

Yes! There are various ways to convert OPUS files to text formats.

The most straightforward way is to do it manually. However, it's not recommended since it will get tedious unless you have very short OPUS lengths.

A second option is to outsource it to a professional transcriptionist. Getting a decent professional will provide the most accurate results. However, they tend to be expensive and have a long lead time. This isn't an ideal route if you're in a hurry or have a tight budget.

The best method is to use automated transcription platforms like Sonix. They can achieve near-human level accuracy using artificial intelligence and natural language processing. Since it's a software tool, the results tend to be fast. Generally, you can expect to get the transcription from a moderate-length OPUS file in as little as 10 minutes.

What are the advantages when you transcribe OPUS to text?

An OPUS speech-to-text transcription might seem like a simple matter. However, it actually has a tremendous impact on your marketing and business operations.

For one, it can increase your audience. People watch videos in various situations, and sometimes they can't rely on the audio. Maybe they're watching on a crowded train and forgot their headphones, or they're in a library and can't turn on the sound. Also, remember that a sizable portion of your market might have hearing disabilities.

In these cases, an OPUS transcription of the video's audio can add subtitles that these viewers can read alongside.

An OPUS to text converter can also break the language barrier. You can translate the transcription into various other languages if you have a video in English. That allows your existing content to reach other markets and territories.

Indeed, some OPUS to text software can even do this for you automatically and in record time. For example, Sonix can convert video files to 39 different languages on the fly.

An OPUS to text converter online can also help you repurpose your content. For instance, you can take an OPUS version of a podcast, then transcribe it into a blog article. You can also hand out transcripts of a webinar to participants.

OPUS to text online converter can also help improve your search engine optimization (SEO) rankings. Search engines don't normally index OPUS files because they can't "read" their contents. Mostly, bots rely on the OPUS's title and description for ranking information, which isn't much. That's like trying to rate an article based on its headline alone.

But by including a transcript, search bots can crawl through the text content of an OPUS file and rank it accordingly. This not only improves your ranking but your OPUS's searchability as well.

Ultimately, a transcript has a dozen uses in your business. And with transcription tools and professional services, you don't have to do it yourself. Some platforms, like Sonix, can even deliver results in minutes. You get to save time, money, and effort while getting an OPUS transcript that can boost your marketing.
