Practical Edge of Speech Technology Moshe Yudkowsky www.Disaggregate.com 2

“Practical” is Relative Affordable Schedule Achievable 3

Core Technology: Speech Recognition (ASR), Text- Engines to-Speech (TTS), Biometrics, Thynometrics (emotions) Data mining, problem Analytics discovery 4

Network Hardware for Speaker Independent 7

Network- based systems: Your equipment (“Premises”)

Network- based systems: “Hosted”

Local Hardware 10

Device- based systems ASR Results Local Recogniti on Known text Complex, personal text

Device- based systems: Hybrid Voice Results Voice to server, data back to device Speaker independent (?) ASR

Engine Speech Recognition (ASR) s Summary: You can do almost anything — but the more you do, the more you pay. 13

Telephony ASR is excellent: Inexpensiv “What city?”— “Amsterdam” “What is wrong with your phone?” — “I dropped it Very on the ﬂoor, and the expensive screen is cracked, and now I can’t see anything.” 14

Cautions No such thing as “speech to text” Speaker dependent comes closest Voicemail to text: human assisted Some telephone ASR is also human assisted 15

Speaker Dependant Desktop computers can do excellent transcription, need corrections Hand-held devices have more memory & power → better ASR 16

Engine Text-to-speech (TTS) s Summary: Available in many languages, reasonable quality, sometimes difficult to understand. 17

TTS requires language understanding and speciﬁc jargon translation: 18

TTS requires language understanding and speciﬁc jargon translation: “Mr.” → “Mister” 18

TTS requires language understanding and speciﬁc jargon translation: “Mr.” → “Mister” “bbl” →“Be Back Later 18

TTS requires language understanding and speciﬁc jargon translation: “Mr.” → “Mister” “bbl” →“Be Back Later “287 m” →“about 300 meters” 18

TTS requires language understanding and speciﬁc jargon translation: “Mr.” → “Mister” “bbl” →“Be Back Later “287 m” →“about 300 meters” Custom voices available 18

Biometrics (Speaker Engine Identification, Speaker s Verification, Speaker Characterization) Summary: Speaker verification practical but still rare; speaker identification & characterization practical and secret 19

Speaker Veriﬁcation (is that really you?) Available, practical Rare in the US, more prevalent in Australia, Israel, and Canada Roadblocks: valid fear; fear of biometrics; love of ﬁngerprints; only part of complete solution 20

•Speaker Identiﬁcation (who are you?) •Speaker Characterization (what are you?) 21

Analytic Data mining, problem s discovery Summary: Surprising useful, expensive 22

Not a real-time process Word searches, “speech to text” Emotion detection by ASR (swearing) and by thynometrics (pitch, volume) 23
