mp3 audio to text

mp3 audio to text

I supposed this is very difficult.
I have a mp3 audio previously recorded. Now I want to convert to text.

Additionally may consist in the discussion between two voices.

What tools can I use to make this work easier ?

Best Regards

There are quite a few tools out there to help. Search for "speech to text". Dragon Naturally Speaking is one. There are more. Most are not free, though there are some free ones. I've only looked into it from a development perspective, so I can't really recommend much on the consumer side. That should point you in the right direction though.

Are you sure Dragon Naturally Speaking is one for transcripting an audio to text.?
DNS is used to dictate from voice to text. But in real mode until I know. Recognizing the voice you have trained before.

They have STT solutions. Not sure if they have consumer level ones there though... But it exists. Samsung bada will have it soon in v2.0 or so.

If I found one I will tell. I'm trying with no good results.
May be a type of experimentating software.

The most accurate transcriptions were of recordings I made in my office, windows closed, with background noise at a minimum. The transcriptions of those recordings were 85 to 95 percent accurate.

5 years ago there were still several STT applications. Most seems to have given up by now, maybe because they can't compete with the Dragon / MacSpeech Dictate or Adobe Audition CSS 5.5. Google Translation includes STT, but it is not yet convincing. Also, Chrome makes Text-to-speak & Speak-to-text become a part of HTML-5, but it is still primitive. If you already have a iPhone 5, it may be the most affordable way to go!

Uffffff Curt.
It's not the same.

The point is transcript an audio with one or more voices to text

audio file to text file

NO SPEECH TO TEXT

Hello Contro ! Software are there like Dragon Natural Speaking and more. But you can also opt for online speech to text services like www.speechtotextservice.com. These services really work great.

I use Dragon NaturallySpeaking 12 Premium.

Yes, Dragon NaturallySpeaking allows you to Transcribe a recorded audio file. See the attached image.

However, let me warn you that the results are not what you would expect or hope for. There is likely to be several errors, missed words, mis-recognized words and if you want a reasonably good transcription, I think you would be disappointed.

I have tried it several times to get a reasonably good MP3 to be processed into text by Dragon NaturallySpeaking without human intervention, but the results contain far too many errors and the subsequent correction process to tidy it up simply takes too long.

The reason for this is multifaceted; the voice model of the speaker may not be available to you (ie - it is not trained to his voice), the MP3 quality may have a lot of background noise, or the microphone was not of a good enough quality or it may be too far away from the speaker's mouth, or he may be speaking too close or too directly into it and it's capturing his breathing sounds and he may slur his speech, or not pronounce words carefully  (ie the speaker is not speaking specifically for speech transcription). There are many factors that contribute to accuracy or lack of accuracy.

Although Dragon NaturallySpeaking has really come of age and doesn't really require that much training in version 12, it does require that you enunciate the words reasonably carefully, without speaking too fast but rather speaking naturally and of course you need a fast laptop as it is quite CPU intensive.

Those people who have used speech transcription will tell you that the most accurate and efficient and effective method is really listen and read back. What that means, simply is that you listen to what the speaker is saying on the MP3 for example and then you speak into a good quality microphone, ie you act as a go between. If you do it this way, then Dragon NaturallySpeaking will give you outstanding results.

However, please take note, it takes approximately about an hour to transcribe 10 minutes of MP3 if you used the listen and read back method.
It is also Critical to make sure that you use a high quality microphone that is attached to a good quality sound card or a good quality USB sound pod.

Another way, is to pay for someone to transcribe for you. Just Google for transcription services.

After all is said and done, you perhaps may still want to just try using Dragon NaturallySpeaking to process the MP3 to see the  whether the results are adequate enough for you.

I'm not sure if Google is still doing their voice to text on YouTube anymore - I've not seen one in a while.

Andrew and I did an interview with Adam Smith on the problem. He's working on a solution, but it has a radically different approach than DNS. However, Andrew took down the site where the interview was, so it's no longer available there, but it looks like it is on iTunes:

Adam explains the problem with the current approaches quite well.

Do you actually need a transcript of speech/discussion, or simply the ability to search for a phrase and the point in time on the recording when that phrase occurs?
If you just want the latter, then slinging the mp3 or wav file into MS OneNote will get it indexed and searchable.

I think is like other ones.
You speak or dictate.
But not for a previously mp3 audio done.
