Version 2026-11-11.
These terms apply when you buy an otoSpeech data pack on oto.earth.
1. Seller
The data packs come from otoearth, Inc., a Delaware corporation, 1876 Bush St, San Francisco, CA 94109, United States ("oto"). Contact: agent@oto.earth.
If you pay by card, the pack is sold through Link, LLC ("Link"), a Stripe company that acts as the merchant of record. Link takes the payment, adds and pays any tax that is due, and sends your receipt and invoice. If you pay by invoice, oto is the seller.
In both cases oto delivers the data, and the Data License is an agreement between you and oto.
2. What you buy
You buy a license to a pack of otoSpeech 1,125h: 100, 250, 500, 750, or 1,125 hours of recorded conversation with its metadata. The Data License sets out what you may do with it.
Packs smaller than the full set are a random selection of sessions. Hours and file sizes shown before purchase are approximate.
3. Who can buy
You may buy for an organization or as an individual. You must be at least 18 years old and able to enter into a contract. If you buy for an organization, you confirm that you may bind it.
You confirm that you are not in a country under a United States trade embargo and are not on a United States government list of sanctioned or restricted parties.
You sign in with a Google account. You are responsible for activity in your account.
4. Price and tax
Prices are in US dollars and do not include tax. At card checkout, Link may show the price in your local currency and adds sales tax, VAT, consumption tax, or similar taxes where they are due. On an invoice, oto adds tax where it must collect it. Where the law makes the buyer account for the tax, the buyer is responsible for it.
The price is the one shown at checkout when you place the order. If a price was shown wrongly by an obvious mistake, oto may cancel the order and refund it in full.
5. Payment and invoice
You can pay by card when you place the order. Organizations can also ask for an invoice and pay it by bank transfer. Payment is handled by Stripe. oto does not receive or store your card number.
If you pay by card, Link emails your receipt and invoice. If you pay by invoice, the invoice is due within 30 days, and oto may cancel the order if it is not paid by then.
To buy against a purchase order, write to agent@oto.earth before ordering.
6. Delivery
Delivery is through Hugging Face. You need a Hugging Face account, and you give its username at checkout. As soon as payment is complete, that account gets access to the repository that holds your pack. For an order paid by invoice, that is when the transfer arrives. Nothing is shipped.
Access is for the account you named. To add or change accounts inside the licensee's organization, write to agent@oto.earth.
Download the files within 90 days of payment. oto may close the access after that. Write to agent@oto.earth if you need it again.
7. Refunds
Because the data is made available as soon as you pay, all sales are final.
If you are a consumer with a legal right to cancel an online purchase, you ask us to deliver at once by placing the order, and you accept that this right ends when the download becomes available.
If a file is damaged or the pack does not match its description, tell us within 30 days of payment. We will replace it. If we cannot fix the problem within 30 days of your message, we will refund what you paid for the affected part.
For card payments, Link may refund a payment under its own rules or where consumer law requires it.
If a payment is refunded in full or reversed, the Data License ends at once. You must then delete the data as the Data License requires, and your access closes.
Nothing in these terms removes rights that the law of your country gives you and that cannot be waived.
8. Notices about your data
We use the notice email you give at checkout to send your invoice, Removal Notices and other updates to the dataset, and your invite to the buyers' group. Keep it current.
9. News about new datasets
Unless you untick the box at checkout, we also email the notice address when oto releases a new dataset. Every such email has a link to stop them.
10. Buyers' group
Each order comes with an invite to oto's private group for otoSpeech buyers. The group is a courtesy and not part of the price. oto may change how it runs or close it.
11. Naming you as a customer
If you buy for an organization, oto may show the organization's name and logo in its list of customers, on its website and in sales material. By placing the order you give oto permission to do this. oto uses them only to say that the organization is a customer, and follows any brand guidelines you send.
To stop this, write to agent@oto.earth at any time. oto removes the name and logo from its website within 14 days and does not add them to new material.
oto does not name individual buyers.
12. Chargebacks and misuse
If a payment is reversed, or an order was placed with a stolen card or false details, oto may suspend the download and end the license.
13. Liability and law
The limits of liability and the governing law in the Data License also apply to these terms.
If you buy as a consumer, the consumer protection laws of your country that cannot be waived still apply, and you may bring a claim in the courts where you live.
Neither party is responsible for a delay caused by events outside its reasonable control.
14. Changes
oto may change these terms for future orders. The version shown at checkout applies to your order.
