 | `ordinal` | | The text is spoken as an ordinal number. The speech synthesis engine pronounces:<br /><br />`Select the <say-as interpret-as="ordinal">3rd</say-as> option`<br /><br />As "Select the third option." |
 | `telephone` | | The text is spoken as a telephone number. The `format` attribute can contain digits that represent a country code. Examples are "1" for the United States or "39" for Italy. The speech synthesis engine can use this information to guide its pronunciation of a phone number. The phone number might also include the country code, and if so, takes precedence over the country code in the `format` attribute. The speech synthesis engine pronounces:<br /><br />`The number is <say-as interpret-as="telephone" format="1">(888) 555-1212</say-as>`<br /><br />As "My number is area code eight eight eight five five five one two one two." |
 | `time` | hms12, hms24 | The text is spoken as a time. The `format` attribute specifies whether the time is specified by using a 12-hour clock (hms12) or a 24-hour clock (hms24). Use a colon to separate numbers representing hours, minutes, and seconds. Here are some valid time examples: 12:35, 1:14:32, 08:15, and 02:50:45. The speech synthesis engine pronounces:<br /><br />`The train departs at <say-as interpret-as="time" format="hms12">4:00am</say-as>`<br /><br />As "The train departs at four A M." |
+| `duration` | hms, hm, ms | The text is spoken as a duration. The `format` attribute specifies the duration's format (*h=hour, m=minute, and s=second*). The speech synthesis engine pronounces:<br /><br />`<say-as interpret-as="duration">01:18:30</say-as>`<br /><br /> As "one hour eighteen minutes and thirty seconds".<br />Pronounces:<br /><br />`<say-as interpret-as="duration" format="ms">01:18</say-as>`<br /><br /> As "one minute and eighteen seconds".<br />This tag is only supported on English and Spanish.|
 | `name` | | The text is spoken as a person's name. The speech synthesis engine pronounces:<br /><br />`<say-as interpret-as="name">ED</say-as>`<br /><br />As [æd]. <br />In Chinese names, some characters pronounce differently when they appear in a family name. For example, the speech synthesis engine says 仇 in <br /><br />`<say-as interpret-as="name">仇先生</say-as>`<br /><br /> As [qiú] instead of [chóu]. |
