Simultaneous interpretation & assistive listening for multilingual events
Our remote simultaneous interpretation tool streams spoken interpretation and assistive listening directly to people’s mobile devices or embedded on your website or app without extra equipment.
Interpret and access translation anywhere
Interpreters can interpret remotely. With a special link, online and in-person audiences can listen to audio translation with their own mobile devices.
Save money and time
With spf.io, you don’t need to buy and maintain interpretation equipment. Using everyday tools like a laptop, microphone, and smartphones, the entire system is accessible through the internet.
Scale to any audience size
Don’t be limited by how many headsets you have anymore. Whether you have 5 people in one event and 1,000+ in the next, spf.io will seamlessly scale to ensure everyone receives the interpretation.
Enable remote interpretation
Remote Simultaneous Interpretation (RSI): Interpreters can join your event from any location to translate live speech and stream their interpretation to people’s mobile devices in real time without extra equipment.
Assistive listening: Provide enhanced, crystal-clear audio through people’s mobile devices. Ideal for people with hearing loss and audiences in overflow or quiet rooms who need a low-stimulation space or want to listen but don’t get a seat in the main room.
Silent stages: Stream your speaker’s audio directly to your audience’s mobile devices instead of using your venue’s loudspeakers. Perfect for events with multiple simultaneous sessions or presentations.
Audience View: Audiences can listen to the audio and see slides and videos by scanning a QR code or visiting a URL on their mobile devices, online and in person. You can also embed the audience view on your website or app.
Increase accessibility with interpreter subtitling
Boost your event’s accessibility by automatically captioning your interpreter’s speech in real time and display it on the big screen and mobile devices. Empower people to fully participate in your event regardless of their abilities and whether they prefer to read or listen to the translation.
Streamline interpretation in one platform
Session resources: Integrate with slides and scripts so interpreters can access prepared content in advance through a single platform.
AI interpreter assistant: Our system can help interpreters if they fall behind by showing a live transcript of what was said.
Scale and grow your audience
Seamlessly accommodate any audience size, from small meetings to large conferences, with 1,000+ participants.
Integrate spf.io with your website or app
Seamlessly integrate your livestream from YouTube, OBS, StreamYard, and more with spf.io or embed the audience view on your web page so your audience can listen to audio translation during your event.

How it works
Remote Simultaneous Interpretation
➊ The interpreter logs into spf.io on their computer and connects their microphone and venue audio.
➋ Meanwhile, your audience visits a URL or scans a QR code on their device (e.g., phone, tablet, etc.) browser to access the audio stream.
➌ The interpreter listens to what the speaker says and speaks their interpretation into their device’s microphone.
➍ The audience listens to the live interpretation on their device.
Assistive Listening or Overflow Rooms
➊ The operator logs into spf.io on their computer and connects their microphone and venue audio.
➋ Meanwhile, your audience, whether in the main room or overflow rooms, visits a URL or scans a QR code on their device (e.g., phone, tablet, etc.) browser to access the audio stream.
➌ The speaker speaks into the microphone, and their audio is transmitted to spf.io.
➍ The audience listens to the audio on their device.
Silent Stages
➊ The operator logs into spf.io on their computer and connects the speaker’s microphone to the system—no loudspeakers needed in the venue.
➋ Meanwhile, your audience visits a URL or scans a QR code on their device (e.g., phone, tablet, etc.) browser to access the audio stream.
➌ The speaker speaks into the microphone, and their audio is transmitted to spf.io.
➍ With headphones plugged in, the audience listens to the speaker’s audio directly from their device quietly and clearly, wherever they are.

Frequently Asked Questions
What’s the difference between audio live streaming and audio description?
Audio live streaming makes sounds and interpretation accessible for hearing people. Meanwhile, audio description makes visual elements accessible to the blind and visually impaired.
You can use spf.io’s Audio Live Streaming for both simultaneous interpretation and audio description. If you want to offer both solutions at your event, ensure you have a qualified audio describer present and create separate channels for each use case. You can contact us to request an audio describer for your events.
Does Audio Live Streaming (ALS) require a tech person?
If you don’t have a tech person, we provide training for your interpreter staff and volunteers on how to set up and leverage ALS. For events, you only need one or two interpreters to operate spf.io. The most critical role to collaborate with is an audio engineer who can ensure high-quality audio is fed into spf.io.
We also provide optional professional services that range from providing live AI translation and captions to post-production of captions and subtitles on videos to developing custom AI models.
What equipment do I need to use spf.io?
Here are the minimum technical equipment requirements to use spf.io:
- Processor: 1.6 GHz Dual-core CPU
- Memory: 4GB RAM / 4GB Free disk space
- Browser: Support for Google Chrome 80
- Operating System: Windows 10 or later, MacOS Mojave or later, or Chrome OS 90 or later
- Network: 1 Mbps download/upload Internet connection speed (when the network is in use during a live event). Test venue internet with an internet speed test.
- Audio: Ability to receive audio input over USB. Learn more about the audio setup here.
These requirements apply to spf.io operators, interpreters, and other producer roles.
Contact us if you have any questions about these requirements.
Can spf.io integrate with existing in-ear translation systems and human interpreters?
Yes, spf.io’s audio live streaming works with existing human interpreters and headsets. If your event runs out of headsets, an interpreter could speak through spf.io, and audience members could listen to the interpretation by plugging their own headsets into their mobile devices and clicking the speaker button within the audience view. This allows for a single point of access for translation/interpretation.
When should I consider interpreter subtitling? Can you provide the interpreters?
Interpreter Subtitling is ideal for Tier 2 languages. For example, auto-translating from English to Mongolian is not good enough but using spf.io to caption an interpreter’s voice improves the quality of the subtitles.
You can contact us to request one of our professional interpreters to do on-site or remote simultaneous interpretation at your event, whether it’s oral interpretation or with interpreter subtitling.
