A set of speech corpora, spoken in both IDS and ADS modes containing similar sentences in terms of complexity, was collected in Sweden and Finland in 2007. Prompts for each language were designed by selecting 10 object words and 10 carrier sentences for each language to produce approximately 100 different sentences. Each sentence was spoken 10 times in adult-directed speech (ADS) mode and 10 ti...

and embedding in ACORNS We describe a bottom-up, activation-based paradigm for continuous speech recognition. Speech is represented by co-occurrence statistics of acoustic events over an analysis window of variable length, leading to a vector representation of high but fixed dimension called “Histogram of Acoustic Cooccurrence” (HAC). During training, recurring acoustic patterns are discovered ...

As urbanization proceeds, natural ecosystems surrounding cities are transformed, but usually some elements persist, notably trees from forest ecosystems. However, it is still unknown the extent to which isolated trees, immersed in an urban matrix, maintain their interactions with insects that feed on seeds. In this work we analyzed pre-dispersal seed predation by two main groups of insects, wee...

this study was aimed to assess the causes of the structural decline in the renewal rate of apristine oak forest close to rome (central italy) by analyzing long-term measurements of the water budget in open and fenced areas. despite dry climate conditions in the area, long-term soil moisture measurements at 100 cm soil depth indicated that an enough large amount of water is available to oaks dur...
