NALscribe is an easy-to-use live speech captioning tool to help people with hearing difficulties understand speech and conversations, designed for use within businesses to increase hearing accessibility and inclusivity for all customers.

National Acoustic Laboratories developed NALscribe to increase understanding and decrease stress levels for the hard of hearing and those communicating with them.

NALscribe is especially beneficial when the person speaking is wearing a mask or face-shield, when communication is more difficult because the lips are hidden and sound is muffled.

Full functionality is available to anyone to download and use - with no restrictions and no cost to install or run.

NALscribe accurately converts speech into text in real-time as a person is speaking. Designed for reception areas (in background noise) or in audiology appointments to support people with hearing difficulties, NALscribe provides continuous speech captioning with no timeout and unlimited minutes. It’s always ready to go and won’t cut out unexpectedly mid-sentence – meaning less time fussing with controls and more time concentrating on clients and your core business.

NALscribe is designed to be used on- or off-line. Slightly higher recognition accuracy is available online, but offline mode can be used for enhanced speech data security / privacy or where no reliable internet connection is available or required.

NALscribe can refresh the screen depending on the environment and privacy requirements
1. Standard mode: text remains on the screen and the entire conversation can be saved to review later - most useful during private conversations and for personal use
2. Privacy mode: text is cleared from the screen 60 seconds after speech inactivity
3. Enhanced Privacy mode: text is cleared after 20 seconds of speech inactivity - most useful in public settings such as reception or enquiry desks

Designed to support communication for anyone with hearing difficulties NALscribe includes features to make communication more accessible for all.

Caption size can be adjusted to be very large to ensure ease of reading. NALscribe also automatically scales other textual content according to the text size user preferences of the device. Very large text is optimal for use in business settings where a common iPad is used to increase accessibility for all customers. VoiceOver is also supported for vision accessibility.

NALscribe has an option to switch to dark mode and includes automatic paragraph formatting of text to improve readability.

NALscribe includes transcription for spoken languages including English (Australia, US, UK and Canada), French, Spanish, Arabic, German, Italian, Japanese, Chinese (Mandarin), Korean, Portuguese, Danish and Russian. Language models can be downloaded to be used offline (with selected devices with iOS13+) at no additional cost, with no limits on use.

Save and share transcriptions to ensure no details are lost from a conversation. Entire conversations can be saved, viewed, edited and added to over time.

Transcripts can be edited on screen or prior to sharing to ensure accuracy, then shared by email or text message through NALscribe, so all participants of the conversation have access.

NALscribe’s profanity filter stops offensive or derogatory language from inadvertently appearing on the screen (English).

NALscribe provides translation (with iOS15+) between 12 supported languages: English (US, UK), French, Spanish, Arabic, German, Italian, Japanese, Chinese (Mandarin), Korean, Portuguese and Russian. Transcribed words and phrases can be selected on screen and a written and audio translation is available. All languages can be downloaded to be used offline and at no additional cost with no limits for use.
