INTERSPEECH 2027

INTERSPEECH 2027 runs 29 August – 2 September 2027 at Pacaembu Oficial in São Paulo, Brazil — the first time the world's largest conference on the science and technology of spoken language has been held in South America. It is organised by the International Speech Communication Association and chaired by Plinio A. Barbosa of the University of Campinas and Sandra Madureira of the Pontifical Catholic University of São Paulo. Interspeech spans speech recognition, speech synthesis, speaker and language identification, spoken dialogue and paralinguistics, and now sits at the centre of the voice-agent and speech-LLM wave. Recent editions have drawn roughly 2,000–3,000 attendees, with a record ~2,700 submissions in 2025 at an acceptance rate near 50%. Satellite events already announced for 2027 include the 14th ISCA Speech Synthesis Workshop and the Blizzard Challenge.

• ✓Speech and audio ML researchers
• ✓Voice AI product leaders
• ✓Heads of AI/ML
• ✓Conversational AI and contact-centre technology leaders
• ✓Applied scientists and research engineers
• ✓Accessibility technology teams
• ✓CTOs in customer-experience platforms

Voice is the interface layer enterprises are rebuilding right now — contact centres, in-car assistants, clinical scribing, real-time translation and voice-authentication fraud defence all depend on it. Interspeech is where the underlying recognition, synthesis and speaker-verification work is published a year or two before it reaches any vendor roadmap, and where the deepfake-voice attack research a CISO will eventually be briefed on first appears. For a VP of AI or a product leader building anything voice-driven, it is the single best place to judge which vendor claims are real, and to recruit specialists who are genuinely scarce.

• ✓Main technical programme of peer-reviewed oral and poster sessions
• ✓14th ISCA Speech Synthesis Workshop (SSW) confirmed as a co-located satellite event
• ✓Blizzard Challenge, the long-running speech-synthesis evaluation benchmark, co-located
• ✓Plenary keynote talks from invited speakers, as in every Interspeech edition
• ✓Tutorials, special sessions and community challenges
• ✓Show & Tell demonstration sessions and an industry exhibit area

• ★The first Interspeech ever held in South America, hosted in São Paulo by general chairs from the University of Campinas and PUC-SP.
• ★The largest dedicated speech-technology conference in the world — a record ~2,700 submissions in 2025 at roughly a 50% acceptance rate, so the programme is genuinely peer-selected rather than sponsor-driven.
• ★Satellite events already announced include the 14th ISCA Speech Synthesis Workshop and the Blizzard Challenge, the field's long-running synthesis benchmark.
• ★Covers the full stack from phonetics and paralinguistics to speech-centric large language models, so acoustic-science and deep-learning work appear in the same programme.
