Voice Demos

At CereProc we like to put our voices through their paces. So rather than the standard "hello my name is..." samples we have chosen material that allows their individual personalities to shine through.

Scottish Voices

CereProc is based in Edinburgh, Scotland and we are very proud of our Scottish voices. The Scottish accent has achieved the highest level of acceptability across a range of accredited surveys. This is one reason Scotland has long been the location of choice for contact centre operations.

The Loch Ness Monster is an alleged creature purportedly inhabiting Loch Ness in Scotland. Popular interest and belief in the animal has fluctuated since it was brought to the world's attention in 1933. Evidence of its existence is largely anecdotal, with minimal and much disputed photographic material and sonar readings. The scientific community regards the Loch Ness Monster as a modern day myth, and explains sightings as a mix of hoaxes and wishful thinking. Despite this, it remains one of the most famous examples of cryptozoology. The legendary monster has been affectionately referred to, by the diminutive, Nessie, since the 1950s.

Islay whisky is Scotch whisky made on Islay, one of the southernmost of the Inner Hebridean Islands located off the west coast of Scotland. Islay is one of five whisky distilling localities and regions in Scotland whose identity is protected by law. There are eight active distilleries and the industry is the island's second largest employer after agriculture. Islay is a centre of whisky tourism, and hosts a Festival of Malt and Music each year on the last week of May, with events and tastings celebrating the cultural heritage of the island.

Labour is blossoming or dancing where The body is not bruised to pleasure soul. Nor beauty born out of its own despair, Nor blear-eyed wisdom out of midnight oil. O chestnut-tree, great-rooted blossomer, Are you the leaf, the blossom or the bole? O body swayed to music, O brightening glance, How can we know the dancer from the dance?

From Among School Children, by William Butler Yeats

Bill Gates, the world’s richest man, has donated $4.6bn (£3.6bn) in the Microsoft founder’s biggest gift to charity since he set up the Bill & Melinda Gates Foundation.

Emotion and character

CereProc is committed to developing innovative new text-to-speech technologies. We believe that speech synthesis could, and should, be used more widely than today. We believe that creating characterful, engaging, emotional voices is the key to making this happen.

Hi, I’m Claire. I study history of art at Edinburgh University. I listen to music a lot, mostly classical, and I love old movies. As for literature, I’m interested in Latin American authors. I’m not in a relationship at the moment. I’d like to meet a caring guy with the same interests as me.

My name is Roger. I run the local neighbourhood watch. This is something which I really dislike. I live on Southend-on-Sea which is a bit awkward. I don’t have many interests but mowing the lawn is an obsession of mine.

I was up late last night reading through the news on my computer and I found a company that can build synthetic speech from almost anything. A great company! Really great, maybe I’d say the greatest company in the world, amazing! Unfortunately I can’t remember their name, I fell asleep while Tweeting about them. God bless America.

Kanske det finaste Sverige kan stoltsera med är den anrika tradition som kallas fika, då man släpper allt man har för händerna och tar en kopp kaffe och möjligtvis en liten munsbit, så som en kanelbulle eller en mazarin. Att samlas runt fikabordet, gärna flera gånger om dagen, är vanligt både på arbetsplatsen och i hemmet. Sverige är ett av de land som konsumerar mest kaffe i världen, men det handlar nog mer om att vara social än koffeinet.
