Russian voice to text online service.

Hi,

We added support of a new language - Russian. So, you can process any of your recordings in Russian now. Just log on SpokenData, submit your data and get automatic text transcript for free in few minutes. Another option is to provide us with URL of YouTube, Vimeo or other on-line services where your data is. We download the data and convert them into text quickly. You are notified by email when the conversion of audio into text is done. You can also edit the transcript yourself in our web editor later.
If you are a developer, feel free to integrate our API. It's easy.

You do not have SpokenData.com account yet? Just register here and you can process your data in 1 minute!

Download recording video, audio and subtitles

SpokenData users can now download processed recording video in mp4, audio in mp3 and recording subtitles in a variety of formats. The files are accessible through the download menu or SpokenData API.

• SRT - SubRip text file format
• TRS - used in Transcriber
• WebVTT - The Web Video Text Tracks Format

Set deadline for your transcription

Do you create/edit the transcription yourself or have a team of annotators? SpokenData has a new handy feature that might help you finish the transcription process in time. From now on, you can select the deadline for each processed recording. Just click on the menu button and select the Set deadline item.

Then, you can order your recordings by the deadline value and see the recordings which should be finished soon. The deadline information can appear in 3 different colors:

• red: deadline has already passed
• orange: deadline will pass within 24 hours
• black: deadline will pass in more than 24 hours

The deadline can always be changed or removed. These feature can also help your annotators who will see how much time they have left to complete their jobs.

Vimeo is supported

As some of our users host their recordings on Vimeo, we now support processing of Vimeo files. Simply enter a Vimeo url into the Media File URL input box. 
In general, users can enter:

• a direct url to a media file (mp3, mp4, mpg, avi, 3gp, mkv, wav and many others)
• YouTube url
• Vimeo url

Besides that, you can also upload a multimedia file using the upload form or SpokenData API.

SpokenData API - Search in Speech

SpokenData API has a new function that enables users to search in recording transcriptions. This means that you can quickly get a list of captions matching the search query with their start and end time, caption content and speaker identity. The search can be performed either in all user recordings or in a list of selected recordings.

An example of a basic SpokenData search API call can be:
http://spokendata.com/api/18/br3sp59a2it7fig94jdtbt3p9ife5qpx39fd8npp/search?q=student

It simply means to search for occurrences of student in all recording transcriptions of the DEMO account.

The returned XML shows the elapsed time for parsing the search query and for performing the search. As the number of results can be very high, the search API call supports paging. By default, the maximum number of results per page is set to 10. In the output XML, there are 2 types of results - recordings and captions. Each has different paging.

How to show the speaker segmentation

In SpokenData subtitles editor, we changed the rule of displaying the speaker segmentation. From now on, it is hidden by default except for the recordings processed directly by the Speaker segmentation method. However, the speaker segmentation can quickly be shown by clicking on the checkbox Show speaker segmentation. Currently, SpokenData subtitles editor does not support editing the generated speaker identity. When it is implemented, we will consider changing this rule.

Interactive waveform with Outwave.js

Outwave.js is a handy library that can render audio waveform in a web browser. Its development was also supported by SpokenData. Apart from that, this library has a great extension for displaying annotation segments directly on the waveform. The segments can be easily added, deleted, merged or split. By and large, we really needed such a library.

Therefore, we are happy to announce that Outwave.js was integrated into the SpokenData subtitles editor. From now on, our users will more easily define speech or non-speech segments just by dragging the segment boundaries on the waveform with the mouse button held down.

We are certain you will benefit from the Outwave library as we do. The fastest way to test our new feature is to start the SpokenData demo and edit any recording subtitles.

New annotation.xml file structure

We have modified the annotation xml file structure. Now it is a way easier to parse. You can get this file through SpokenData API. See this short example:

<segment>

<start>63.25</start>

<end>65.40</end>

<speaker>A</speaker>

<text>Hello, this is the first caption</text>

</segment>

<segment>

<start>72.92</start>

<end>74.49</end>

<speaker>B</speaker>

<text>and here comes the second one</text>

</segment>

Start and end tags represent the subtitle appearance time in seconds. We store values with precision of 2 decimal places. Speaker tag identifies the person who is speaking. It can keep whatever alphanumerical value. And the text tag serves for storing the subtitle content. 

You can see a live example from the SpokenData demo here:

Interactive audio waveform

From now on, when you play any recording, you will see an interactive waveform on the left of the transcription. The waveform is only displayed on larger screens with a minimum horizontal resolution of 1220px. The waveform can significantly help you detect moments of speech. When you click into it, the player seeks to that exact moment.

This audio waveform viewer for the web can be downloaded from https://github.com/vdot/outwave.js.
