2026 Updated ITU‑T Testing Charges｜P.1140 and P.1110 In‑Vehicle Voice Test Price Analysis

ITU‑T stands for International Telecommunication Union’s Telecommunication Standardization Sector which releases P‑series communication standards. ITU‑T itself does not issue formal certificates. So‑called ITU‑T certification means third‑party labs conduct tests following ITU‑T standards and issue test reports. Car head‑units, conference equipment and smart speakers with voice‑calling features commonly need P‑series compliance testing. This article breaks down all related expenses clearly.

1. What Items Does ITU‑T Testing Cover

Three widely‑adopted ITU‑T P‑series standards apply for automotive products: P.1110 governs regular broadband hands‑free calling for vehicle multimedia systems; P.1140 sets specifications for eCall emergency‑call voice transmission; the older narrow‑band P.1100 standard gets phased out for new projects; P.1120 is for conference speakers and portable hands‑free devices.

Testing content consists of these key parts: transmit voice quality (speech clarity from users to recipients), receive‑side voice quality, echo cancellation, double‑talk performance and background‑noise reduction against engine, tyre and wind noise inside cars. All evaluation results rely on objective scoring instruments instead of subjective judgements.

·Narrow‑band devices adopt PESQ with a maximum MOS score of 4.5; broadband and VoLTE products use POLQA with a full score of 5.0. Most vehicle OEMs accept MOS scores above 4.0 as qualified while readings over 4.5 count as excellent.

·Echo‑cancellation performance (ERLE) must reach at least 30dB; audio‑loss duration under double‑talk scenarios should not exceed 200ms.

  2. Cost Composition of P.1140 Testing

Lab‑service fees make up the only expense. Unlike other certification schemes with registration or yearly fees, ITU‑T testing only charges for lab work and delivers final reports stating standard numbers and test outcomes afterwards.Full P.1140 testing including transmitter‑side, receiver‑side, echo‑cancellation, double‑talk and noise‑suppression items costs roughly 150,000 RMB. If you only select basic transmit‑and‑receive tests, total costs can drop to around 50,000 RMB.

P.1110 shares partial test items with P.1140 yet needs vehicle‑acoustic‑environment simulation or real‑car testing, so its overall cost is 20‑30% higher ranging from 70,000‑200,000 RMB. Labs usually offer bundled discounts of 20,000‑30,000 RMB if you complete both P.1110 and P.1140 tests together, which is a cost‑effective choice for suppliers whose OEM clients demand both standards.

  3. Core Factors That Influence Total Expenses

·Vehicle‑acoustic‑simulation costs for P.1110 testing: Labs without dedicated cabin simulators rent real‑world vehicles at a daily rate of 1,000‑2,000 RMB for a normal 3‑5‑day test cycle with total rental costs between 3,000‑10,000 RMB. Facilities equipped with standard cabin‑simulation hardware avoid such charges entirely.

·Lab‑selection differences: Full P.1140 testing from Germany‑based HEAD‑Acoustics headquarters costs over 200,000 RMB. China‑based partner labs authorised by HEAD charge 30‑50% extra while local Chinese compliance labs offer services between 50,000‑100,000 RMB with equally valid data, though some international vehicle manufacturers only accept reports from HEAD‑branded equipment.

  4. Cost Trends in 2026

With increased lab capacity across China, overall P.1140 and P.1110 testing prices trend slightly downwards in 2026. Top‑tier labs keep pricing stable while medium‑sized testing institutes cut their charges by 10‑15% due to intense market competition.

New‑energy vehicle manufacturers treat in‑car voice interaction as selling points and raise MOS‑score requirements from 3.5 up to above 4.0. Higher score targets lead to longer debugging cycles and push overall project costs higher accordingly. Besides standard P‑series tests, some automakers order customised assessments for speech‑recognition rates under specific speaking speeds, multi‑person voice separation and dialect compatibility which generate additional separate fees.

Test reports have no fixed expiry dates technically, yet vehicle‑makers require reports issued within the past 12 months. If firmware updates modify voice‑algorithm logic, you have to re‑run tests to match reports with mass‑production firmware versions. We recommend fresh voice‑quality testing after major firmware upgrades.
