Phone Interpretation Cost Benchmark
We collected primary-source public OPI rate cards. The sample spans $0.60–$1.75/min for human interpretation before certain fixed fees, compared with $0.30/min for TalkTool AI translation.
What does over-the-phone interpretation cost in 2026?
In TalkTool Research's August 2026 public-contract sample, published human OPI rates run from $0.60 to $1.75 per minute before applicable fixed fees. The range is not a universal market average: it depends on contract, language, volume, and service level. TalkTool's published AI phone-translation rate is $0.30/min. The underlying public contracts, scopes, and raw data are linked below so the comparison is reproducible.
Key Facts
- Sampled public human OPI rates range from $0.60–$1.75 per minute
- The $0.60 rate is in a Hawaii statewide contract effective through May 2027
- A public LanguageLine agreement lists $1.30–$1.75/min by volume, plus certain fixed fees
- TalkTool's published AI rate is $0.30 per translated minute
- The usage-rate gap in this sample is 50%–83%, before applicable fixed fees
What public contracts say over-the-phone interpretation costs
Published human OPI pricing is usually hard to find. We collected the rate cards in two public-government agreements and normalized the per-minute charges to USD. The result is a transparent benchmark, not a claim about every buyer's negotiated rate.
The public records show a much wider range than the usual generic "$3 per minute" shorthand: $0.60–$1.75 per minute for human, on-demand phone interpretation in the sampled rate cards. TalkTool's public AI phone-translation rate is $0.30 per translated minute.

Each number below comes from a primary-source public contract. You can download the exact CSV we used or inspect the original PDFs. Rates are shown before taxes and before any applicable fixed fees.
| Contract / provider | Scope | Published rate | Source |
|---|---|---|---|
| Hawaii PL 26-19 / Effectiff | Top 14 requested languages | $0.60/min | State contract |
| Hawaii PL 26-19 / Effectiff | All other or unlisted languages | $0.65/min | State contract |
| Hawaii PL 26-19 / Bromberg | Top 14 requested languages | $0.95/min | State contract |
| Hawaii PL 26-19 / Bromberg | All other or unlisted languages | $1.15/min | State contract |
| Yamhill County / LanguageLine | 0–1,000 minutes per month, all spoken languages | $1.75/min | County agreement |
| Yamhill County / LanguageLine | 6,001+ minutes per month, all spoken languages | $1.30/min | County agreement |

Fixed fees can change the effective cost of short calls
Per-minute rates are comparable only when the billing rules are made visible. The sampled LanguageLine agreement lists a $50 monthly minimum per client ID, a $0.25 platform-access fee per call, and a $5 third-party dial-out fee per call in addition to its per-minute usage rate. The Hawaii contract, by contrast, says connection time is not chargeable and begins billing when the interpreter starts interpreting.
What TalkTool's $0.30/min comparison does — and does not — mean
At the usage-rate level, $0.30 is 50% below the lowest sampled human OPI rate ($0.60) and 83% below the highest sampled entry rate ($1.75). That is not a substitute for a human interpreter in a clinical, legal, or other high-stakes setting. It is a clean way to price routine, operational multilingual calls where AI is appropriate.
How we built this asset
We searched for primary-source, public U.S. government agreements that explicitly list on-demand over-the-phone interpreting rates. We recorded only named OPI line items in USD, preserved the original language and volume scope, and excluded VRI, onsite, document translation, taxes, and fees from the rate-range calculation. The data was collected August 29, 2026 and is intentionally a small, auditable sample — not a market-wide average.
