App Store Description

SRAVI brings a voice to the voiceless.

SRAVI (Speech Recognition for the Voice Impaired) produces speech by reading your lips, for those who can’t vocalise words. SRAVI only works with a limited phrase list of 20 words that have been deemed useful for patients in need of AAC.

People who need AAC may include those who’ve had: tracheostomies, trauma, stroke, paralysis or other medical conditions.

You can use SRAVI yourself, or with a carer or relative. Using the camera on your smartphone, the app records a short video of your lip movements and performs automatic lip-reading to verbalise what you said.

The phrase list of 20 words that SRAVI understands is displayed above.

SRAVI can be customised to adapt your personal lip movements, which means it works well for people who move their lips differently due to a medical condition.

If you can hold your phone yourself, then you can use SRAVI to produce sounds based on your lip movement. This can help communicate at home, at the shops or if it's too noisy to be understood.

SRAVI also helps relatives and carers communicate with those who can't vocalise words in hospital, for example in ICU.

SRAVI is more natural than typing or writing on paper. It allows people who can't vocalise words to find a new voice.

SRAVI is a brand-new lip-reading app launched in 2020. The app assists people who have vocal impairments.

SRAVI is provided as a subscription service.

To use SRAVI you must purchase an auto-renewable subscription. You can use the app as a Free Trial for 2 months from the purchase date. You can cancel the subscription at any time up to 24 hours before the end of 2-month trial and you will not be charged.

The subscription will appear in your account as "SRAVI Basic Monthly" and is charged at £9.99 per month, or your local currency equivalent.

Your subscription will be charged to your iTunes account at confirmation of purchase and will automatically renew monthly unless auto-renew is turned off at least 24 hours before the end of the current period.

Current subscriptions may not be cancelled during the active subscription period; however, you can manage your subscription and/or turn off auto-renewal by visiting your iTunes Account Settings after purchase.

SRAVI is made by Liopa Ltd.

SRAVI will record a video of your face for the purpose of lip reading only. SRAVI will only record video when you press the record button on the 'Read My Lips' screen.

Video data captured through the SRAVI app is sent securely to Liopa for processing and a response is returned to your app. After processing, the data may be retained to help SRAVI learn an individual’s lip movements and improve future lip-reading accuracy for that user. Liopa do not share this data with any third parties. Video data may also contain audio, for future use in audio-assisted speech recognition. Users can enable or disable the capture of audio at any time by logging into the app and navigating to the Settings screen.
