What if we used poetry to teach computers to speak better?

McGill linguist's findings show how languages differ in their use of emphasis

A better understanding of how we use acoustic cues to stress new information and put old information in the background may help computer programmers produce more realistic-sounding speech.

Dr. Michael Wagner, a researcher in McGill's Department of Linguistics, has compared the way French- and English-speakers evaluate poetry, as a way of finding evidence for a systematic difference in how the two languages use these cues. "Voice synthesis has become quite impressive in terms of the pronunciation of individual words," Wagner explained.

"But when a computer 'speaks,' whole sentences still sound artificial because of the complicated way we put emphasis on parts of them, depending on context and what we want to get across."

A first step to understanding this complexity is to gain better knowledge of how we decide where to put emphasis. This is where poetry comes into play. Wagner has looked at prosody, which means the rhythm, stress and intonation of speech. Poetry relies heavily on prosody, and by making a comparison between languages, he is able to uncover how prosody functions differently in English and French.

Working with Katherine McCurdy at Harvard University, Wagner recently published research that examined the use of identical rhymes in each language. "These are rhymes in which the stressed syllables do not just rhyme, but are identical, such as write/right or attire/retire," Wagner explained. "It is commonly used in French poetry, while in English poetry it is considered to be unconventional and even unacceptable." Wagner gave the following example from a book by John Hollander:

The weakest way in which two words can chime
Is with the most expected kind of rhyme —
(If it's the only rhyme that you can write,
A homophone will never sound quite right.)
The study shows that identical rhymes fit into a general pattern that also applies outside of poetry: even when repeated words differ in meaning and merely sound the same, the repeated information should be acoustically reduced, otherwise it sounds distinctly odd. "It's sort of a bug of the way English uses prosody," Wagner said, "but one that hardly ever creates a problem, because it occurs so rarely in natural speech." Wagner is now working on a model that makes better predictions about where emphasis should fall in a sentence given the discourse context. His findings were published in the journal Cognition and received funding Quebec's Fonds de recherche sur la société et la culture and a Canada Research Chair in Speech and Language Processing grant.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
