According to Market Research Future, the simultaneous interpretation market will reach $2.5 billion by 2025, with annual growth of 6.8%. This increase reflects growing demand for language solutions suited to international events.
Integrating simultaneous interpretation systems has become indispensable to overcome language barriers and ensure smooth communication.
Here is a guide to choosing and implementing these solutions effectively. For cross-border conferences, our Strasbourg agency provides booths and accredited interpreters.
Understanding the interpretation systems available
Three main technologies meet the needs of international conferences:
- Traditional interpretation: Maximum accuracy, suited to demanding environments such as diplomatic negotiations and medical conferences.
- AI solutions: Flexibility and speed, ideal for webinars and hybrid meetings.
- Velotype (live captioning): Greater accessibility, especially for participants who are hard of hearing.
According to the International Association of Conference Interpreters (AIIC), 73% of international events use a combination of these solutions to meet the varied needs of participants.
Traditional interpretation with a booth
Interpretation booths remain a standard for events requiring absolute linguistic accuracy.
- Booths compliant with the ISO-4043 standard: They guarantee minimum soundproofing of 45 dB.
- Audio equipment: An ideal frequency range between 125 Hz and 12,500 Hz ensures optimal sound quality.
- Infrared or radio-frequency technology: Infrared systems suit large rooms, while radio frequency offers better range.
These technologies are particularly suited to conferences with high technical or legal stakes. These set-ups are the norm for congress organisation in Paris, where the audience is often multilingual.
AI interpretation solutions
Technological advances have made AI accessible for simultaneous interpretation.
- Accuracy: Around 85 to 95%, depending on the languages and the complexity of the subject.
- Latency: Reduced to 2-3 seconds, which allows a near-instant experience.
- Language support: Up to 30 languages at the same time.
These solutions are used by:
- 45% of webinars,
- 30% of hybrid meetings,
- 15% of in-person conferences.
Although AI does not fully replace human interpreters, it is an economical alternative for less complex events.
Selection criteria and budget
The choice of solution depends on several factors: the type of event, the number of participants and the budget. Here is an estimate of the costs:
Traditional interpretation (2 languages)
- Fewer than 100 participants: €2,000-€3,000 per day (2 interpreters, basic equipment).
- 100-300 participants: €3,000-€5,000 per day (4 interpreters, reinforced equipment).
- More than 300 participants: €5,000-€8,000 per day (6 interpreters, full infrastructure).
AI solutions (5 languages)
- Fewer than 100 participants: €1,000-€2,000 per day.
- 100-300 participants: €2,000-€3,500 per day.
- More than 300 participants: €3,500-€5,000 per day.
Velotype
- Daily rate: €800-€1,500.
- Multilingual transcription: +50% of the total cost.
These estimates include equipment hire and technical support.
Technical infrastructure required
To guarantee smooth interpretation, the technical requirements must be met:
- Bandwidth: 100 Mbps recommended for digital solutions.
- Network latency: Below 100 ms to avoid interruptions.
- Loss rate: Less than 0.1%.
- Redundancy: A dual internet connection is indispensable to ensure continuity of service.
A prior technical audit is essential to validate the compatibility of the equipment with the event venue.
Selecting and managing interpreters
The skills of the interpreters are at the heart of a successful multilingual conference.
- Recruitment: Hire certified interpreters, specialised in the subjects covered (medical, legal, scientific).
- Coordination: Prepare a detailed briefing on the programme and the specific terminology.
- Management: Plan for two interpreters per booth, alternating every 20-30 minutes to maintain the quality of the interpretation.
A well-trained team guarantees accurate interpretation and a better experience for participants.
Modern solutions for greater flexibility
Innovative technologies simplify the organisation of multilingual events:
- Remote interpretation apps: Particularly suited to webinars, they remove the logistical constraints linked to travel for interpreters.
- Videoconferencing systems: Integrating simultaneous interpretation, these platforms allow worldwide participation while reducing costs.
These tools are particularly interesting for hybrid or fully virtual conferences.
Practical management during the event
Even with careful preparation, real-time management is crucial:
- Technical support: A team on site must monitor the equipment and quickly resolve any problem.
- Participant feedback: Gather opinions from the start of the event to adjust the settings if necessary.
These measures guarantee smooth translation and optimal participant satisfaction.
Impact of simultaneous interpretation
Investing in simultaneous interpretation systems offers several advantages:
- Greater engagement: Participants fully understand the presentations and interact more effectively.
- Brand image: Offering a multilingual experience shows a genuine commitment to inclusion and professionalism.
With solid planning and the right tools, simultaneous interpretation turns your international conferences into inclusive, successful events.
