The quality and speed of your internet connection may affect the speed and quality of your transcription. With a slow or bad/intermittent internet connection the transcription may be delayed or missed words.

The Captional app streams small packets of audio to our transcription server, once the audio is converted to text it’s sent back as even smaller packets of text. If watching Netflix uses about 8 Mb/second of data, Captional uses 0.4 Mb/second. That’s pretty small. Which means it will work on a slower internet connection.

Yes. Imagine you’re having an outdoor wedding and there is no WiFi. Captional will still work using your phone's mobile data. The sender and receivers do not have to share a network, in fact, if you have the Room Code for an event, you can access the captions on the other side of the world.

No, Captional does not use very much data. To send an audio stream to be captioned uses about 360kbps. One hour of transcription uses about 180 MB of data.

On average, with a good internet connection it takes about 0.3 to 1 second for spoken words to be transcribed and displayed on screen.

Yep. For this reason, please do not rely on Captional in emergencies or especially sensitive situations.

Captional uses AI or Artificial Intelligence to generate captions, with no human involvement. Since AI can make mistakes, we think it’s best suited for the small screen.

In the same way that listening to someone speak English with an unfamiliar accent may be difficult for you, the AI transcription accuracy may suffer. However, because of how the AI is trained, in some cases it may actually have a clearer understanding of what’s being said.

Under ideal conditions the AI model is very accurate, but you will notice that the AI transcription will make mistakes that a human would not.

While the AI model does use some contextual clues, words that sound similar such as cold, colt and cult may be interchanged, resulting in a rather unusual sentence. You and I will know the difference, and given the context, will likely understand what was meant.

The AI model Captional uses was trained to understand many different accents and dialects, however, it can be phonetically very literal, so if you say “just” with a Wisconsin accent that sounds like “jest”, Captional may use the word “jest”.

One more thing that real-time captioning in general does not do well, is sentence structure. Most commonly real-time captions will interpret a pause in speaking to indicate the end of a sentence. Speakers frequently use dramatic pauses in the middle of sentences for emphasis. Captional frequently gets this wrong.

In our testing the best way to improve accuracy was to move the microphone closer to the speaker. Making this change increases the volume of the speaker relative to the background noise.

If you’re using Captional in a setting that has a PA (sound system) the best way to get clear audio is to use the sound board as your source. Use a dedicated BUS to isolate the speaker from other unmuted channels. If it’s all Greek to you, ask your sound person, they will know what this means.

If you’re using Captional without a sound system, we recommend using a clip-on wireless microphone or a Bluetooth microphone. We have a few favorite wireless microphones that might work with your mobile phone.

Translation is done through artificial intelligence (AI). Its purpose is to give you the gist of what’s being said in a language that the viewer is more comfortable with. As with any system, if bad information goes in, bad information goes out. Wrong words in the original transcript may create an even more confusing translation. To improve the quality of your translations you first need to make sure your original transcript is as accurate as possible by speaking clearly into a close microphone.

Captional uses state of the art AI transcription models that run on very sophisticated servers. The servers, data bandwidth, and development cost money to use. Monthly fees also enable us to provide exceptional support.

The Captional program streams the audio input to be transcribed in the cloud. Every quarter second a section of audio data is sent to the transcription server and the transcription server sends back a text packet. The Captional server then forwards that text packet on to any device that’s connected to your stream.

All of this happens in about 250 milliseconds or less. It’s pretty amazing!

Currently Captional costs $50.00 US per month per account, or $550 per year. Organizations that require more than one Room Code will need to create an additional account for each Room Code.

No. We only keep the audio packets long enough for transcription and then they disappear. We also do not store your transcriptions.

Yes. After you end a session, your transcript is available to download from your account.

On the streamer page, click the Session History icon in the top right. From there, you can view, rename, and download transcripts from your past sessions at any time.

There is no overall limit to the number of people who can view captions simultaneously.

Our Premier plan supports up to 25 simultaneous viewers, and plans can be set up for larger audiences based on your needs and venue size. Viewer limits are determined by your plan, not by Captional’s technology.

No. Captional is a cloud service, so the text stream can be accessed anywhere in the world that there is an internet connection. Please let me know if you’re using Captional at the North Pole; that would be very cool.
