Text To Speech Voice Search 2009 Conference Paolo Baggia 12

Loquendo TTS Text To Speech Multi-language: 26 languages, 62 voices and more coming! Truly Natural and Expressive sounding voices for highly Emotional pronunciation: Commonly used phrases such as How are you? or You ve got to be kidding! and paralinguistic events such as yawning, coughing and laughing and to confirm, exclaim, thank, express doubt, etc.) Reading Styles and specialized support (e.g. addresses, SMS, etc.) Audio Mixer: to have complete control over all audio sources (including sampling rates and coding) audio files can be mixed, looped, faded in/out, and synchronized with synthetic speech Mixed Language Capability: Language Guesser: that automatically identifies the language of any text so that by means of Phonetic Mapping: any of Loquendo s voices can correctly pronounce any foreign word (e.g. English words in an Italian text) Voice Creator tool for new voice generation TTS Director for designing effective prompts and Lexicon Manager tool for creating personalized user lexicons Voice Search 2009 Conference Paolo Baggia 13

Loquendo TTS Director Loquendo TTS Director is a complete development environment for creating your own voice prompts, and for designing your own personalised voices. Target: clients wanting to edit their prompts at a more complex level and adjust parameters with far more precision, as well as to add pauses, phonetic transcriptions, and tailor-made lexicons for atypical pronunciation. Voice Search 2009 Conference Paolo Baggia 14

Loquendo TTS Tools: Lexicon Manager Loquendo Lexicon Manager helps to define the pronunciation of foreign language words, toponyms, proper names, acronyms, abbreviations, etc. The virtual keyboard helps to write the phonetic transcriptions Sections for different languages in the same lexicon Future support for the PLS (Pronunciation Lexicon Specification) standard format Voice Search 2009 Conference Paolo Baggia 15

Automatic Speech Recognition Voice Search 2009 Conference Paolo Baggia 16

Loquendo ASR Automatic Speech Recognition A reliable speaker independent technology Broad Vocabulary & Flexible Recognition - recognizes up to 1,000,000 words; supports isolated and continuous speech even in the noisiest environment such as wireless Highly Accurate Speech Recognition - thanks to integration of neural networks and hidden Markov models, and detailed acoustic-phonetic units trained on large speech corpora Multi-language speech recognition (20 languages) Barge-in capability to guarantee high reactivity and robustness to noise and background speech; Garbage rules definition to match arbitrary spoken sequences not modeled by the grammar Powers Loquendo Speaker Verification Tool package that automatically analyzes data collected in the field to improve service performances, including: Acoustic Model Adaptation (to the environment, speaker, channel adaptation, etc.) Phonetic Learning to identify frequent formulations that have not been covered and additional pronunciation variants Voice Search 2009 Conference Paolo Baggia 17

Loquendo ASR Automatic Speech Recognition Either HMM (Hidden Markov Models) or NN (Neural Networks) for core algorithms. Loquendo ASR combines both approaches, giving high performance, and increased efficiency with large vocabularies. ASR efficiency reduces hardware costs: lower PC-power requirements enables more recognition channels to run simultaneously. Loquendo ASR is so efficient that core ASR engine is used on embedded platforms. e.g smartphones, navigation devices. Extended Standards Support future-proofs customer investments: MRCP compliancy (for client-server architectures); complete support for grammar standards, such as W3C SRGS & SISR, enables optimization for VoiceXML applications; support for AURORA DSR (for distributed speech recognition); A highly accurate phonetic transcriber enhances recognition results. Loquendo ASR based on same phonetic transcriber as Loquendo TTS - tested both automatically and by painstaking human listening. Loquendo Speaker Verification - an extension to ASR module - combines both speaker and knowledge verification (i.e. matches what was said with who said it ). Voice Search 2009 Conference Paolo Baggia 18

Learn to distinguish a best-in-breed ASR from those not up to the job Key Factors For Success ASR Tuning e.g. to the environment, to the speaker Tools enabling ASR to learn from the field - avoids need for costly professional services e.g. Acoustic Model Adaptation Tool, Phonetic Learning Tool, De-noising module - improves performance in noisy environments by cleaning the signal while computing spectral parameters Loquendo ASR specialized tasks, including: Word Spotting - recognizes keywords in audio streams; Garbage Rules definition enables free speech, simplifying grammars and application development, matches expressions like Um, Er, "Well", "Let me think", etc., giving greater flexibility and a more natural interaction experience. Voice Search 2009 Conference Paolo Baggia 19

Loquendo ASR SDK Tool Suite Evaluation Kit Tool to select recorded audio material: Offline execution of recognition tests Statistics about recognition performance Semantic parsing over text strings Acoustic Model Adaptation Tool to efficiently adapt the recognition engine to difficult conditions, such as: different audio channels (wireless, multimedia microphone, PDA, etc) different environments (in-car, public areas, factory) application-dependent vocabulary (specific jargon, such as aeronautical terms) ways of speaking (regional accents, fast speech) Phonetic Learning Tool to improve performance using data collected in the field to deal with: additional linguistic formulations complex speech recognition applications non-native speakers or regional accents Voice Search 2009 Conference Paolo Baggia 20
