Meeting Room

LiveSmart Video Chat main facility is a video chat between an organizer and one or more attendees. The organizer role can be performed by tutor, doctor, support personnel, real estate agent, car reseller, registered user in a social media, etc
In order a call to be performed, both parties need to be online in one room. You can generate rooms for your customers in a couple of ways:
– Add a code snippet to your browser pages, so a contact button appears and informs your visitors that you are online;
– Generate a room from the Dashboard page. You can add room ID, visitor name (if you are expecting someone to come), password if you want this room to be protected and organizer name;
– Make the link to be dynamically generated by your system;

When both parties are available, visitor will either be prompted for name/email/password (it depends on the configuration) or directly joined to the room.

Contact Button

The contact button is the way your customers can request a video call or a simple chat session. It is also a presence indicator showing if you are online. You can check the detailed instructions on how to set a button in your site here.

Another way to contact someone is to send him a visitor link. It can be generated from the Organizer page and can contain different information.

Video/Audio Calls

LiveSmart Video chat provides two modes for the video chat session. The default is “conference” mode, and is enabled in the config/config.json file with videoScreen.videoContainerStyle: "conference". Meeting style is organized like a Zoom session.

Broadcast

There is one or more broadcaster and many viewers. This is a perfect tool for online lecturers and enterprises.

From admin dashboard you can generate links for the broadcaster – it will open in new tab and the viewer link will be stored in the clipboard.
There can be more than one broadcaster – just use the broadcast URL from another device.
If you save a short URL, the broadcaster link is automatically saved too, with “b” letter added at the end. If you have saved organizer URL as agenturl, the broadcaster URL will be agenturlb.
Check here with demo/demo how you can generate broadcasting URL.

Speech-to-text, Text-to-speech and Translate

LSV offers the possibility to transcribe voice to text, or the speech recognition module. It can be enabled from Configuration section of your Dashboard. The default language of the speech recognition is English. All the list of available languages can be seen here.
In addition to the speech recognition, there is a possibility to translate the transcribed text. You need to have a Google API key. In this tutorial is described how to get it.
After you get the key, it needs to be set in transcribe.apiKey: API_KEY. The organizer language should be set in transcribe.language and the visitor in transcribe.languageTo. The last parameter transcribe.direction can have three values – both, agent or visitor. When used both, the translation goes in the two directions – from agent (organizer) to visitor and vice versa. When set to agent, the organizer speech will be translated from transcribe.language to transcribe.languageTo in the visitor screen.

If direction is visitor, then the visitor speech will be translated from transcribe.languageTo to transcribe.language in the organizer screen.

transcribe demo

While typing a chat message your attendee will receive voice. This functionality can be combined with the translation module. For example, you speak in Spanish, your attendee will receive subtitled message and voice in English. Text to speech, together with the speech to text and the translation modules provide the ultimate facility for multilanguage video session tool.
